View source for List of glitches in Generation VIII

{{GlitchResearch|Checking which glitches have been since fixed}}
This is a '''list of glitches''' that occur in the [[Generation VIII]] [[core series]] [[Pokémon games]].

==Sword and Shield==
===All versions===

====Baton Pass Own Tempo glitch====
If a Pokémon with {{a|Own Tempo}} is confused due to obtaining it from {{m|Baton Pass}}, it will not be cured of confusion until after a Pokémon takes its turn (uses a move, switches out, etc.).

This glitch was also present in the [[core series]] [[Generation]] {{gen|V}}, {{gen|VI}}, and {{gen|VII}} games.

====Berry tree glitch====
This glitch involves shaking a Berry tree from behind. It ultimately allows for the player to walk through walls.
{{YouTubeEmbed|NFmgCQepj9Q|BLAINES|berries}}

====Charge Beam additional effect chance glitch====
{{main|Charge Beam additional effect chance glitch}}
If the user has {{a|Serene Grace}} and uses {{m|Charge Beam}} while its side is under the effect of the rainbow from the combination of {{m|Fire Pledge}} and {{m|Water Pledge}}, the additional effect chance for Charge Beam will overflow and become 24%.<ref>[https://www.smogon.com/forums/threads/sword-shield-battle-mechanics-research.3655528/post-9076566 Post by Sasa to Sword & Shield Battle Mechanics Research on Smogon Forums]</ref>

This glitch is present in the [[core series]] [[Generation]] {{gen|V}}, {{gen|VI}}, {{gen|VII}}, and {{gen|VIII}} games.

====Curry cloning glitch====
When getting wild Pokémon spawns in Pokémon Camp, after a curry, there's a chance that the Pokémon near the player staring at the wild Pokémon will act like a wild Pokémon, and will be eligible to "re-join" the team. The Pokémon must have a long hitbox (like a tail, or a long body in general) and have a floating idle animation to be eligible for the glitch. Upon re-joining the team, it'll be cloned, with some alterations. Game of origin, OT, OT ID, Poké Ball used, date caught, level caught, location caught will all be altered to match the player's current status, and it'll receive the Curry Connoisseur mark, even if it already has another mark, or if it shouldn't be normally eligible to receive it. The held item will also be cloned, as long as the player doesn't remove it before receiving the Pokémon.

If the player does re-accept the Pokémon in the party, the wild Pokémon will start roaming the player's Pokémon Camp, still with the ellipsis balloon over its head. However, it'll disappear once the player leaves Camp, or after doing another curry.

Some of the confirmed Pokémon to be eligible for this glitch are {{P|Salamence}}, {{P|Giratina}}, {{P|Moltres}}, {{P|Weezing}}, {{P|Corviknight}}, {{P|Flygon}}, {{P|Noivern}}, and {{P|Steelix}}.
{{YouTubeEmbed|F4EzowTRWRA|SpikeOriundo}}
====Dragonite moveset oversight====
Due to {{p|Dragonite}}'s level-up moveset being internally not ordered properly, it will not learn {{m|Outrage}} by gaining levels. It is still recognized as move learned at level 41 for purposes of [[Move Reminder]] or the [[wanderer]] found at the [[Ballimere Lake]].<ref>https://twitter.com/SnorlaxMonster/status/1726220806580277522</ref>
====Evolution cancelling glitch====
If the {{player}} cancels [[evolution]] of a Pokémon, the proper stamp will appear on the [[Y-Comm]] regardless.

====Galarian Stunfisk breeding bug====
For the purposes of [[regional form]] inheritance via {{pkmn|breeding}}, {{rf|Galarian}} {{p|Stunfisk}} is not considered a regional form of Stunfisk. As such, if both Unovan and Galarian Stunfisk are parents and both hold [[Everstone]]s, only Unovan Stunfisk will ever hatch, regardless of the mother's form.<ref>https://twitter.com/Sibuna_Switch/status/1404287033628106753</ref>

====Glimwood Tangle trade/Mystery Gift bug====
{{GlitchResearch|How does it look like when receiving a Mystery Gift while in the Glimwood Tangle? Can this glitch be done in other locations as well (except Ballonlea)?}}
If the player is currently in the [[Glimwood Tangle]], the [[trade]] and [[Mystery Gift]] screens will look differently than normal.
* On the trade screen, the Poké Ball hologram over the Pokémon given by the player is disabled, and the background of the trade screen is darker. The part of the screen that shows the received Pokémon is unaffected.

{{YouTubeEmbed|mL3RDJ2osQQ|ChickasaurusGL|fairy|psychic}}

====Ingredients seller glitch====
When the {{player}} cycles behind an ingredients seller he will turn around. He can then quickly go back round behind him and interact without him turning back again. When the player talks to him, his back will be turned to them. 
{{YouTubeEmbed|04pqLjnhWZQ|Poke-MunkPresto}}

====Isle of Armor Pokédex glitch====
If the player brings a Pokémon that was introduced as part of the Isle of Armor expansion from Pokémon HOME, the in-game Pokédex would not update to add its entry. The only workaround at the time was to deposit the Pokémon into the Nursery and taking it back so the Pokédex would register it. This was fixed when the Switch version of Pokémon HOME was updated to version 1.1.1.

====Judge display glitch====
When viewing a Pokémon's stats in the box, the + button will not cycle to the Judge display if the Pokémon is held above a slot containing an Egg, nothing, or a menu option. 
{{YouTubeEmbed|EcncNiQottM|Flametix|fire}}

====Location glitch====
At certain precise locations, entering a battle causes the game to believe the player is in the wrong area when the battle ends. This can be exploited to catch weather-dependent Pokémon, or obtain Pokémon with an impossible encounter location such as the Meetup Spot.<ref>[https://docs.google.com/document/d/1ALMSCAPSbiG_DaJqLa2idkzBbA_leLy0rtANOqPornA Pokémon Sword/Shield Bingus Zone (Location Glitch)]</ref>

====Memory feeling off-by-one bug====
The feeling displayed in a Pokémon's {{OBP|memory|game mechanic}} for Pokémon transferred from [[Generation VI]] are displayed incorrectly. Pokémon that display the feeling "it was happy" in Generation VI instead display an empty string<ref>[https://twitter.com/Sibuna_Switch/status/1329519268967436289 "Larvitar remembered being happy when it was in Pokemon Y. After traveling through Bank and HOME to Pokemon Sword, the memory of being happy is gone."]</ref> (or the same as the last checked Pokémon's feeling if another Pokémon's memory has been checked<ref>[https://twitter.com/Sibuna_Switch/status/1334770576372719617 "The memory of feeling happy in Gen 6 turns into a blank feeling, which has some unusual behavior!  If another Pokémon's memory is viewed, the blank memory copies the feeling if it is viewed right after. This is purely visual and reverts when the game is rebooted."]</ref>), and all subsequent feelings are displayed as a different feeling, shifted by one with respect to their index number.

This is due to the fact that in the Generation VI games, feelings are indexed from 0, while in the Generation VIII games, feelings are indexed from 1. Since the internal value storing the feeling in a Pokémon's memory is neither modified when a Pokémon is [[transfer]]red from Generation VI to Generation VIII through [[Pokémon Bank]] and [[Pokémon HOME]] nor specially handled in Pokémon Sword and Shield, the displayed feeling appears to have been changed despite the internal value remaining unchanged.

====Memory place change bug====
The places displayed in a Pokémon's {{OBP|memory|game mechanic}} for Pokémon transferred from [[Generation VI]] with memories that mention places introduced in {{g|Omega Ruby and Alpha Sapphire}} (such as "a Secret Base", "a Contest Spectacular Hall", or "oh, while soaring in the sky") are displayed incorrectly. For example, a {{p|Terrakion}} with a memory of being caught at the [[Pathless Plain]] would display in Omega Ruby and Alpha Sapphire as being caught at "a tiny island", but this memory would display as being caught "in a Secret Base" once transferred.

This is due to the fact that these strings are listed in a different order internally compared to Omega Ruby and Alpha Sapphire. Since the internal value storing the place in a Pokémon's memory is neither modified when a Pokémon is [[transfer]]red from Generation VI to Generation VIII through [[Pokémon Bank]] and [[Pokémon HOME]] nor specially handled in Pokémon Sword and Shield, the displayed place appears to have been changed despite the internal value remaining unchanged.

====Move Reminder glitches====
These glitches occur when attempting to use a Move Reminder when there are at least 67 available moves (e.g. this can be done with a {{p|Mew}} which previously knew many Technical Records). It can cause the game to halt on an error message, closing the software. Other times, the player is able to see a glitched move (sometimes with a blank name, other times "———"). This glitch was found by SciresM.
{{YouTubeEmbed|e6iig5Z9YqE|ChickasaurusGL|sword|shield}}

====Night Daze oversight====
When used, {{m|Night Daze}} damage will not be accounted for on the target's HP bar for the rest of the turn, unless the move has caused the target to faint or something else changes its HP.

====Overworld Symbol encounter Gender Ratio bug====
All overworld [[symbol encounter]]s are forced to have a 1:1 gender ratio, excluding 100% Male, 100% Female, and [[Gender unknown]] species.

====Rose Tower glitch====
This glitch occurs when the player flies to another location from the outside of Rose Tower before going inside the tower itself. The map shows the objective "Search for the bad League staff member hiding around Wyndon Monorail Terminal!" despite having already done so by this stage of the game. This area is no longer accessible and prevents the story from progressing as the player has no other means of going back to Rose Tower. This glitch was found by hikaribruh.

====Rotom Bike turning radius glitch====
When the player uses the [[Rotom Bike]]'s turbo boost, its turning radius becomes larger. If the player speaks to an NPC, a [[Pokémon egg]] hatches, picks an item on the ground or opens the menu or the [[Y-Comm]] during a turbo boost, the bike will continue to have a larger turning radius despite the boost stopping prematurely. The radius will reset if the player uses a second turbo boost, enters or exits a body of water or gets off and back on the bike.

====Shiny animation glitch====
If multiple [[Shiny Pokémon]] are on the player's team during a [[Max Raid Battle]], upon one of them fainting and being sent back into the battle, all of the Shiny Pokémon will play the Shininess animation again.

====Silvally Move Tutor glitch====
{{p|Silvally}} is programmed to be able to learn all 3 Pledge moves; however, the Move Tutor offers only {{m|Grass Pledge}}, not {{m|Fire Pledge}} or {{m|Water Pledge}}.

This glitch is also present in {{pkmn|Ultra Sun and Ultra Moon}}.

====Stat rollover glitch====
If a [[stat]] is 655 or higher after applying the [[nature]] multiplier, it rolls over and becomes the result {{wp|modulo operation|modulo}} 655. Consequently, a stat that is exactly 655 rolls over to 0. A defense stat of 0 causes [[damage]] calculation to evaluate to 0 when it should divide by defense, preventing a division by zero error. The formula adds 2 after dividing by defense, so attacks do exactly 2 damage if there are no other modifiers.

This glitch exists because stats are stored in an unsigned 2-byte integer. For HP, this is done before adding the level to the stat, but for other stats, the rounding is done after applying the nature multiplier. A beneficial nature multiplies the stat by 110, and a hindering nature multiplies the stat by 90. Then, the stats affected by the nature are divided by 100 and rounded down. The part where the calculation multiplies by 110 may cause an overflow, hence the stat rollover.

This was impossible before this generation outside of battle, as natures didn't exist before [[Generation III]]. At the time, the highest non-HP stat was {{p|Shuckle}}'s Defense or Sp. Def (both at 230), which, before dividing by 100, could only reach a maximum value of 61,490, which is not enough to cause an overflow that could occur if it exceeded 65,535 (the maximum value for unsigned 2-byte integers). Shuckle held this stat record until Generation VIII.

====Summary Max Move display glitch====
[[File:Gigalith Max Move glitch.png|thumb|The glitch in effect for Gigalith]]
When a Pokémon is [[Dynamax]]ed, if the {{player}} looks at the party screen, the moves will be listed as if the Pokémon weren't Dynamaxed (Example: {{m|Rock Slide}}, {{m|Rock Blast}}, {{m|Sandstorm}}, {{m|Stone Edge}}). However, when checking the summary screen, the moves are displayed as [[Max Move]]s, in this case, {{m|Max Rockfall}} (three) and {{m|Max Guard}}.
{{-}}
====Symbiosis glitch====
If an [[item]] can be consumed during switch-in, {{a|Symbiosis}} will activate it twice and consume the item that it passes.

====TM06 display bug====
[[File:TM06 error SwSh.png|thumb|TM06 error]]
Despite being a [[TM]], [[File:Bag TM Flying VI Sprite.png]]{{TM|06|Fly}} is displayed as a [[File:Bag HM Flying VI Sprite.png]]{{type|Flying}} ''[[HM]]'' instead.
{{-}}

====Trade Completed notification glitch====
After a surprise trade has been concluded, if the Y-Comm is opened fast enough and the player starts another Surprise trade, the trade completed notification will still show (although the next trade completion will make it stop).

====Trick Room oversight====
If a Pokémon has an effective speed greater than 1809, it will ignore the effects of {{m|Trick Room}}, and act before slower Pokémon. This glitch also exists in [[Generation V]], [[Generation VI|VI]] and [[Generation VII|VII]].
{{YouTubeEmbed|x26255FOrAA|Morbuen|sword|shield}}
====Vulpix Area info oversight====
When viewing {{p|Vulpix}}'s Area page, it will show that it can spawn in the [[Giant's Cap]], although it can only spawn there in {{g|Sword}}, and only as a [[Max Raid Battle]] boss.

====Wild Area News glitches====
=====April 28, 2020 Error Move Hydro Pump Drilbur Wild Area News event=====
[[File:Drilbur Hydro Pump Sh.png|thumb|250px|Drilbur using Hydro Pump]]
[[File:Drilbur Hydro Pump Summary.png|thumb|250px|Summary page displaying the error move Hydro Pump]]
{{main|Wild Area News/2020#April 28 to May 11, 2020|Wild Area News/2020 → April 28 to May 11, 2020}}
{{main|Game move errors#Unobtainable moves|Game move errors → Unobtainable for the generation → Unobtainable moves}}
For a portion of the first day of this round of the Wild Area News for April 28 to May 11, 2020, 1★ Drilbur raids originating from {{pkmn|Shield}} came with the illegal move {{m|Hydro Pump}}. The same raids for the rest of the event's duration, or from {{pkmn|Sword}}, came with the correct move, {{m|Scratch}}.

The reason for this error was likely a typo, as [[List of Pokémon with form differences#Rotom|Wash Form]] {{p|Rotom}} appeared in the adjacent entry in Shield's version of the event data, with Drilbur receiving Hydro Pump instead of Rotom.

In Shield, the move slots were assigned for 1★ raids in the following order:
{| class="roundtable" style="margin: left; text-align: center; background: #{{shield color}}; border: 3px solid #{{shield color dark}}"
! Pokémon || Move 1 || Move 2 || Move 3 || Move 4
|-
| {{MSP/HOME|0529|Drilbur}}{{p|Drilbur}} || {{m|Mud-Slap}} || {{m|Metal Claw}} || {{no}}<br>{{m|Hydro Pump}} || {{m|Hone Claws}}
|-
| {{MSP/HOME|0479W|Rotom}}{{p|Rotom}}<br><small>([[List of Pokémon with form differences#Rotom|Wash Form]])</small> || {{m|Double Team}} || style="background:#999" |'''?'''<br>{{m|Discharge}} || {{m|Thunder Shock}} || {{m|Confuse Ray}}
|}

In Sword, the entry occupied by Wash Form Rotom was replaced with Heat Form Rotom instead, however Sword's version of the event data did not contain a similar error, with both Pokémon receiving correct movesets. The move slots were assigned for 1★ raids in the following order:
{| class="roundtable" style="margin: left; text-align: center; background: #{{sword color}}; border: 3px solid #{{sword color dark}}"
! Pokémon || Move 1 || Move 2 || Move 3 || Move 4
|-
| {{MSP/HOME|0529|Drilbur}}{{p|Drilbur}} || {{m|Mud-Slap}} || {{m|Metal Claw}} || {{yes}}<br>{{m|Scratch}} || {{m|Hone Claws}}
|-
| {{MSP/HOME|0479O|Rotom}}{{p|Rotom}}<br><small>([[List of Pokémon with form differences#Rotom|Heat Form]])</small> || {{m|Double Team}} || {{yes}}<br>{{m|Overheat}} || {{m|Thunder Shock}} || {{m|Confuse Ray}}
|}

Note that while {{m|Discharge}} is a valid move for Wash Form Rotom, Sword's counterpart Heat Form Rotom received {{m|Overheat}} instead. Additionally, in 2★ through 5★ raids in Shield, Wash Form Rotom had Hydro Pump in its moveset, and in 1★ through 5★ raids in Sword, Heat Form Rotom had Overheat in its moveset, this heavily implies that Hydro Pump was intended to be in 1★ Wash Form Rotom's moveset.

Players who caught a Drilbur with Hydro Pump cannot trade or battle online with it unless that move is forgotten; after doing so, it cannot be relearned.

These erroneous Drilbur otherwise function like other Drilbur, and can evolve into {{p|Excadrill}} with Hydro Pump. Additionally, while [[Dynamax]]ed, these Drilbur and Excadrill also have access to {{m|Max Geyser}}, which is typically unobtainable as neither can legitimately learn any {{t|Water}}-type attacks.

=====June 30 to July 31, 2020 Wild Area News event glitches=====
When the June 30 to July 31, 2020 [[Wild Area News]] event began, (Wild Area News [[Index number]] 27), it contained an error in which a nonexistent item, ([[Dynite Ore]], which was not present in the game prior to the release of [[The Crown Tundra]]), was part of the item drops awarded for completing a Max Raid Battle tied to the event. The game attempting to reward the player with the nonexistent item caused a glitch that crashed the game after viewing the item drop list. 

This glitch was fixed after a few hours, in two separate stages. The first stage, (Index number 28), removed the nonexistent item from the ''normal_encount'' item pool and replaced the reference to the ''bonus_reward'' item pool containing the bugged item. This did not fully fix the glitch as the bugged item was still present in the ''bonus_reward'' item pool, (despite no longer crashing players with the reference removed), and as a result, it was unavailable server-side, with the glitched raids being unable to be hosted or joined if the player had connected online via the [[Y-Comm]].

The second stage, (Index number 30), removed the bugged item from the ''bonus_reward'' item pool as well, and replaced the item and references to the correct item, [[Armorite Ore]].<ref>https://projectpokemon.org/home/files/file/4212-wild-area-event-20-july-2020/</ref>

=====Wild Area News rewards list glitch=====
[[File:Wild Area News item glitch.png|thumb|The glitch in effect (affects [[Nugget]]s here)]]
When the player finishes a Max Raid Battle induced by an event or [[Wild Area News]], some list items on the list of rewards will be shown separately.
{{-}}

===Version 1.0.0 only===
====Sucker Punch/Quash glitch====
In a [[Double Battle]] where the player who didn't initiate the challenge is down to their final Pokémon, that Pokémon's {{m|Sucker Punch}} or {{m|Quash}} will fail when used against the opponent on their right. This applies regardless of what move the Pokémon selected for the turn.
With the release of the version 1.1 update to [[Sword and Shield]], this glitch was fixed and Sucker Punch and Quash can now correctly hit Pokémon in that position.

===Version 1.1.0 only===
====Fairy Lock crash====
In Pokémon Sword and Shield v1.1, if a Pokémon uses {{m|Fairy Lock}} while animations are enabled, the game crashes. In link battles, where battle animations are mandatory, both players' game would crash. Due to no Pokémon that can learn the move being present in Pokémon Sword and Shield at the time of this glitch's existence, the only way for this to legitimately occur is when the move is called via {{m|Metronome}}.

The crash does not occur if animations are disabled. This crash was not present in Pokémon Sword and Shield v1.0, and was fixed for v1.1.1.

===Version 1.0.0 to 1.2.1 only===
====Hacked Max Raids====
Earlier versions of the game failed to perform basic legality checks on Max Raid data received from other players. As such, if a player were to spawn a Max Raid against a [[glitch Pokémon]] via [[cheating]] methods and choose to invite others, other players would actually be able to join the battle and even catch the glitch Pokémon. This glitch Pokémon could then be used in an exploit involving the Daycare and the PC box to clone Pokémon and held items. Due to the involvement of a glitch Pokémon and the potential to duplicate items, these raids have often been known as "[[Missingno]] raids", even though Missingno itself only exists in [[Generation I]].

This glitch was patched in version 1.2.1.

====Menu glitch====
A glitch which allows the player to move the cursor in a frame just before using an Experience Candy or starting an evolution. This applies the item/evolution sequence to the other Pokémon, and allows for major consequences such as evolving underleveled Pokémon (if the first Pokémon is of the same species), male {{p|Salandit}}, {{p|Combee}} (which become female {{p|Salazzle}}, {{p|Vespiquen}}), special event Pokémon that normally cannot evolve but can be forced to via level up and this glitch (involving event {{p|Meowth}}, {{p|Eevee}}) and Pokémon inside Eggs. If the species do not match, or evolution is impossible, the game may halt on an error message; closing the software.

The glitch appears to have been patched in v1.2.1.
{{YouTubeEmbed|BGhfc3tFd0M|ChickasaurusGL|items}}

===Version 1.0.0 to 1.3.1 only===
====Rollout storage glitch====
{{main|Rollout storage glitch}}
If a Pokémon uses {{m|Rollout}} against a {{p|Mimikyu}} with intact {{a|Disguise}} or an {{p|Eiscue}} in Ice Face mode, the game will not properly reset the Rollout bonus after the move ends, allowing it to be applied to a different move. This glitch also exists in [[Generation VII]]. This glitch was fixed in the version 1.3.1.

====Toxic sure-hit glitch====
{{main|Toxic sure-hit glitch}}
If a {{type|Poison}} Pokémon uses {{m|Toxic}}, any subsequent moves that Pokémon uses in the same turn (possible by using Toxic via {{m|Instruct}} or {{a|Magic Bounce}}) will always hit including when the target is in a [[semi-invulnerable turn]]. This glitch also exists in [[Generation VI]] and [[Generation VII|VII]]. This was fixed with the release of version 1.3.1.
{{YouTubeEmbed|fW0-nLf6mz4|WeedleTwineedle|sword|shield}}

===Version 1.3.0 to 1.3.2 only===
====Groudon/Kyogre Trick glitch====
In previous generations, {{m|Trick}} and {{m|Switcheroo}} would properly fail if they would attempt to take a [[Red Orb]] away from {{p|Groudon}}, take a [[Blue Orb]] from {{p|Kyogre}}, or give either of those Pokémon the correct colored orb. Neither Primal Reversion nor the colored orbs exist in Pokémon Sword and Shield, and Trick and Switcheroo's checks were modified so that it would fail if one of these Pokémon is involved and either the user or the target is not holding an item, instead of checking if they are holding the correct colored orb.

This glitch did not prevent Groudon or Kyogre from having an item stolen by {{m|Thief}}, {{m|Covet}}, {{a|Pickpocket}}, or {{a|Magician}} and being left with no item afterward, or from somehow stealing an item themselves by one of these means. Other Pokémon that previously had specific items that would make Trick and Switcheroo fail, but are no longer supported (such as Mega Stones), were unaffected by this glitch.

This glitch was patched in update 1.3.2.
<!-- ==Pokémon HOME== -->

==Brilliant Diamond and Shining Pearl==
===Battle Tower Capsule glitch===
[[Ball Capsule]]s will not have their animations play in the [[Battle Tower (Generation IV)|Battle Tower]]. This glitch notably only applies to the player's side of the field; any Ball Capsules used by the opponents will work as normal.

===Cloning Pokémon and held items===
This allows the player to duplicate any Pokémon of their choosing, as well as their held items, by utilizing a glitch which allows the player to walk around in the overworld while the [[Menu|"X" menu]] remains on screen. This is achieved by going into the [[Party|"Pokémon" sub-menu]], checking a Pokémon's summary, and pressing ZL and ZR nearly simultaneously. The player can then back out into the overworld with the "X" menu on screen and walk around. Various methods to duplicate Pokémon have been documented.

The menu glitch was patched in version 1.1.2, making these methods of duplication impossible without hacking. However, some other methods of the menu storage involving pressing X while pushing a boulder with {{m|Strength}} or showing the {{m|Fly}} map still exist, and hence their related glitches can still be done.

===Glitch sticker===
[[File:BDSP Glitch sticker.png|thumb|Receiving a glitched sticker.]]
In version 1.0.0, the TV producer in [[Jubilife TV]] can award a glitched blank sticker at a 1/64 chance.

The event script "ev_c01r0203_sunglassesb_03_SEAL_BURNING_A", which attempts to award Burning Sticker A, appears to be corrupted.
If the game randomly picks Burning Sticker A as the sticker to be awarded, the {{player}} instead receives a glitched blank sticker without a name instead.

This glitch was fixed by version 1.1.2, which correctly awards Blazing Sticker A instead.{{-}}

===Memory leaks and sound engine failure===
Lingering in certain menus and screens for an extended period of time can cause the sounds of the game to stutter, and eventually cut out entirely, or cause significant framerate issues, eventually leading to a game crash. 

Notably, the Ball Capsule decoration and preview screens, as well as the post-Contest screen can cause the music and Pokémon cries to stutter and eventually stop working, and scrolling through the Pokédex for an extended period can cause framerate loss and eventually crash the game.

===Pokémon spawning in rocks===
It is possible for a [[Symbol encounter|wild Pokémon]] to spawn inside a rock in the [[Grand Underground]]. Such a Pokémon  will notice they player if they approach it, but it will be unable to chase after the player.
{{YouTubeEmbed|pOeRruV2yLg|Megalorex|Brilliant Diamond}}

===Pokétch glitches===
Some [[Pokétch]] apps don't behave in the intended way.
====Calculator====
The Pokétch's Calculator app was reported to exhibit wonky behavior when the language is set to one that uses commas for decimals and periods for representing thousands.<ref>[https://www.reddit.com/r/pokemon/comments/r0lv82/not_that_anyone_would_use_it_but_the_calculator/?utm_medium=android_app&utm_source=share Reddit post from u/K0nr4d to r/pokemon <!-- the subreddit's actual name -->from 23 November 2021]</ref>

If the decimal point is present, the pre-decimal part can be changed by new inputs, and is also not involved in calculations either. The calculation ignores the pre-decimal part and then removes the decimal point from the result, effectively multiplying the result by <math>10^n</math>, where <math>n</math> is the number of decimal places before the multiplication.

====Counter====
If the player encounters a wild Pokémon, the number on the Pokétch's Counter app resets to 0.<ref>[https://www.reddit.com/r/pokemon/comments/r20ydz/is_the_counter_poketch_app_broken_or_am_i_just/?utm_medium=android_app&utm_source=share Reddit post from u/GizmoMojo to r/pokemon from 25 November, 2021]</ref>

====Cries====
Like in the original Sinnoh games, when typing in a Pokémon's Pokédex number and then confirming, their [[cry]] will play, provided that the player has that Pokémon registered in their Pokédex (e.g. entering 1 will play Bulbasaur's cry). However, when the [[DS Sounds]] are activated, entering 493 won't play Arceus's cry for some reason.

===Snowpoint Gym slope oversights===
====Reaching Candice early====
The {{player}} can use diagonal movement to climb slopes in the [[Snowpoint Gym]]. Using them, it's also possible to reach [[Candice]] without battling any other Gym Trainers.<ref>[https://vm.tiktok.com/ZM8tXKJ5m/ "How long did you spend?" video on TikTok by @wigglydoe from 28 November, 2021]</ref>
====Softlocking====
Using diagonal movement, it is possible to softlock oneself in the Gym, due to an apparent oversight (as the puzzle was probably never designed for diagonal movement).

===Spinda spot pattern glitches===
[[File:USUM BDSP Spinda Comparison.png|thumb|An example of a {{Shiny}} Spinda, showing inconsistent spot patterns when viewed in {{g|Ultra Sun and Ultra Moon}} (left) and {{g|Brilliant Diamond and Shining Pearl}} (right), despite having identical [[encryption constant]]s.

[[File:HOME Mobile v2.1.1 vs v3.0.0 Spinda Comparison.png|thumb|An example of a {{Shiny}} Spinda, showing inconsistent spot patterns when viewed in {{pkmn|HOME}} v2.1.1 (left) and HOME v3.0.0 (right), despite having identical [[encryption constant]]s.

[[File:HOME0327 s.png|thumb|The static rendered image of {{Shiny}} Spinda from Pokémon HOME, used in all menus of Pokémon HOME's Switch and mobile apps.]]
When determining {{p|Spinda}}'s spot pattern, Spinda's [[encryption constant]] should be read as a {{wp|Endianness|little-endian}} value. However, Brilliant Diamond and Shining Pearl instead mistakenly read it as a big-endian value, effectively reading the bytes in the opposite of the intended order, causing the spot pattern to be rendered incorrectly. For example, a value of <code><span style="background:#FF9999">12</span><span style="background:#9999FF">34</span><span style="background:#99FF99">56</span><span style="background:#FFFF99">78</span></code> (hexadecimal) would be interpreted as <code><span style="background:#FF9999">78</span><span style="background:#9999FF">56</span><span style="background:#99FF99">34</span><span style="background:#FFFF99">12</span></code> instead.<ref>[https://twitter.com/Atrius97/status/1500557458623778819 @Atrius97]</ref> Due to this bug, Spinda is not allowed to be transferred between these games and [[Pokémon HOME]].<ref>[https://twitter.com/SerebiiNet/status/1526896501653381122 @SerebiiNet]</ref>

In [[Pokémon HOME]] v3.0.0, an additional glitch appeared in the mobile app version of HOME. In HOME v2.1.1 and prior versions, when opening the [[summary]] of a Spinda in the mobile app, Spinda would display the correct spot pattern, identical to its appearance in [[Generation VI]] and below. In HOME v3.0.0, all Spinda were displayed as having the same pattern as the static rendered image used in all HOME menus, appearing to use the encryption constant <code><span style="background:#FF9999">7A</span><span style="background:#9999FF">39</span><span style="background:#99FF99">78</span><span style="background:#FFFF99">66</span></code>,<ref>https://twitter.com/Atrius97/status/1676088622943207424</ref> regardless of the Spinda's actual encryption constant value.<ref>https://twitter.com/Atrius97/status/1665787431009001472</ref> 

The encryption constant of Spinda in HOME remained unchanged, (which meant that if transferred out of HOME into a compatible game, they would have likely retained their original spot pattern), however HOME's mobile app no longer displayed the spot pattern associated with the encryption constant of a given individual Spinda, all appearing identical to the "stock" rendered image of Spinda. This was resolved in v3.0.1.<ref>https://twitter.com/Atrius97/status/1676088622943207424</ref>

Additionally, in Brilliant Diamond and Shining Pearl's [[Super Contest]]s, the encryption constant is generated randomly, instead of using the value from Pokémon the player selects. As a result, if the player selects a Spinda, it will appear with completely random spot patterns for the duration of the contest, regardless of its true spot pattern.<ref>https://twitter.com/Sibuna_Switch/status/1828258413442142257</ref>

===Surf glitch===
This glitch involves using {{m|Surf}} right when a Trainer challenges the {{player}} into a battle. After winning the battle, the Surf popup will appear, and if the player selects "Yes", they will be able to surf on land.
====Catching Shaymin====
On {{rt|224|Sinnoh}}, it is possible to use Surf just as the {{tc|Black Belt}} Carl spots the player and challenges them to a battle. After winning the battle, the player will be able to Surf on land and therefore reach the [[Seabreak Path]], and eventually the [[Flower Paradise]] with {{p|Shaymin}} without the requisite items.<ref>[https://www.youtube.com/watch?v=9_zDbZ7xA70 GLITCH: Catch Shaymin Early in Pokémon Brilliant Diamond & Shining Pearl With This Trick (Guide) Nov 27, 2021]</ref>

==Sword, Shield, Brilliant Diamond and Shining Pearl==
===Pokémon as Eggs bug===
[[File:BDSP Egg glitch.png|thumb|A Pokémon referred to as an Egg]]
If the player names a Pokémon "Egg", the game sometimes refers to the Pokémon as an actual {{pkmn|Egg}}.
{{-}}
===Pokémon Egg Shiny Roll bug===
When {{pkmn|breeding}}, if any [[personality value]] rerolls are applied, (such as the additional shiny rolls provided via the [[Masuda method]] or [[Shiny Charm]]), the initial roll to generate a personality value is skipped.<ref>https://twitter.com/SciresM/status/1319805906691842050</ref><ref>https://twitter.com/SciresM/status/1319799153162006530</ref>

The result is that when breeding using the Shiny Charm alone, it only provides 2 total rolls for the personality value, meaning there is approximately a 2/4096 (equal to 1/2048) chance of hatching a Shiny Pokémon. This is a reduction from prior generations where the initial roll and both rerolls are accounted for, which would provide a shiny rate of 3/4096, (approximately 1/1365).

When using the Masuda method alone, despite the Masuda method being intended to provide 7 total rolls (1 initial roll, and 6 rerolls) (equal to 1/585) which is 1 more reroll than prior generations, it is reduced to 6 rolls total (no initial roll, 6 rerolls), effectively canceling out the additional reroll and providing a 6/4096, (approximately 1/683), chance of hatching a Shiny Pokémon as usual.

*However, in [[Generation VIII]], due to the Masuda method providing one more reroll than in previous generations, the chance of hatching a Shiny Pokémon when using both the Shiny Charm and Masuda method is unchanged, providing 8 total rolls, (instead of the intended 9 for a Shiny rate of 9/4096 (equal to 1/455)), for a Shiny rate of 8/4096 (equal to 1/512) as usual.

==Legends: Arceus==
===All Versions===
====Characters/tents graphical expansion glitch====
Circling [[Irida]] in the [[Pearl Settlement]] will cause nearby tents and characters to start expanding.<ref>[https://www.youtube.com/watch?v=NQXEBUEL9m0&t=36s The 7 BEST Glitches in Pokemon Legends Arceus Feb 15, 2022]</ref>

====Invisible Pokémon glitch====
Pokémon in the overworld or from [[resource node]]s may be invisible. If a player catches an invisible overworld Pokémon, they may be able to catch the non-invisible counterpart and effectively duplicate the Pokémon.<ref>[https://www.youtube.com/watch?v=NQXEBUEL9m0&t=174s The 7 BEST Glitches in Pokemon Legends Arceus Feb 15, 2022]</ref>

[[File:Legends Arceus move type display glitch.png|thumb|The glitch in effect]]
====Move type display glitch====
During a battle, when both the user and target of a move faint (without ending the battle), all moves shown on the party screen will be displayed as if they were {{type|Normal}} and ineffective (i.e. displaying the "No effect" caption).<ref>[https://twitter.com/KeyacomYT/status/1510319862408695809 @KeyacomYT]</ref>{{-}}

====No damage glitch====
If the player pulls up the map at the exact moment they take damage and fast travel, they will no longer take any damage and won't be able to drown in water.<ref>[https://www.youtube.com/watch?v=NQXEBUEL9m0&t=222s The 7 BEST Glitches in Pokemon Legends Arceus Feb 15, 2022]</ref>

====Re-encountering Pokémon====
If the {{player}} finds any shaking [[resource node]]s with a Pokémon inside them (trees, crates, tumblestone deposits, etc.), the player can get the Pokémon to jump out by throwing a [[Poké Ball (Hisui)|Poké Ball]] with a Pokémon inside it at the shaking resource node. After the encounter, if the player goes inside of a cave or cavern (going back to [[Jubilife Village]] will cause this not to work) within the current map and waits for 30 minutes, the player can return back to the same resource node, and find exactly the same Pokémon inside it that they found before.<ref>[https://www.youtube.com/watch?v=NQXEBUEL9m0&t=100s The 7 BEST Glitches in Pokemon Legends Arceus Feb 15, 2022]</ref>

====Rotom model glitch====
Heat Form {{p|Rotom}}'s model may get stuck with the door of its oven open.
{{YouTubeEmbed|umnxmPLsQE8|channel/UCGXpbMrGR8BqCwZtKhWc1Dw|name=illustrious rocket|electric}}

====Shiny Giratina crash glitch====
If a {{Shiny}} Origin Forme {{p|Giratina}} uses {{m|Shadow Force}}, the game will crash. This is due to Origin Forme Giratina having special animations for using Shadow Force, which are not programmed for its Shiny variant. As a result, the Shiny Giratina will begin executing the move but the game will crash upon attempting to load the animation partway through.
{{YouTubeEmbed|nSpPsAiUEYA|channel/UCGXpbMrGR8BqCwZtKhWc1Dw|name=illustrious rocket|ghost}}

====Snowpoint Temple levitation glitch====
While in [[Snowpoint Temple]], the player character and others such as [[Adaman]] can be seen levitating off the ground.

====Super speed glitch====
If the player gets hit by a wild Pokémon while stumbling down a cliff that is too steep to climb, they will get super speed.<ref>[https://www.youtube.com/watch?v=NQXEBUEL9m0&t=382s The 7 BEST Glitches in Pokemon Legends Arceus Feb 15, 2022]</ref>

====Thundurus crash glitch====
During the battle with {{p|Thundurus}}, the game may crash.

===Versions 1.0.0 - 1.1.0===
====Cresselia sequence break====
{{p|Cresselia}} may be found in the wild before the player receives the mission to capture them, which normally would cause her to begin spawning. If she is captured before receving the mission, she will never be recognized as captured for the fulfillment of the mission, preventing the player from progressing further in the story.<ref name="sequence break">[https://www.youtube.com/watch?v=NQXEBUEL9m0&t=312s The 7 BEST Glitches in Pokemon Legends Arceus Feb 15, 2022]</ref>
===Versions 1.0.0 - 1.0.2===
====Lake guardians sequence break====
Due to a glitch, it is possible for one of the [[lake guardians]] to re-appear after capturing it. Doing so will increase the relevant mission flag again; while this does not prevent from progressing in the mission and receiving the [[Draco Plate]], it stops any further lake guardians from spawning, making it impossible to catch all Pokémon on that save file without trading.

===Versions 1.0.0 - 1.0.1===
====Cherrim glitch====
After {{p|Cherrim}} has changed form, it would become impossible to catch.
===Version 1.0.1===
====Overcast Cherrim glitch====
Cherrim will remain in its Overcast Form even in sunny weather. This glitch first appeared after the glitch that rendered Cherrim impossible to catch once it changed form was fixed.
