===Slow Start oversight===
In the Japanese versions, removing {{a|Slow Start}} (via moves like {{m|Skill Swap}}, {{m|Worry Seed}} or {{m|Gastro Acid}}) does not undo the Attack and Speed drop. This was fixed in the localizations.

===Starly defeating starter Pokémon oversight===
During the first battle of the game with the player's [[starter Pokémon]] against a wild Starly, if the player's Pokémon reaches red/low HP (20% or lower), Starly is programmed to flee instead of attack so that the player does not lose. [[Critical hit]]s also do not occur in this battle. However, under specific circumstances it is possible for Starly's Tackle to hit the player's Pokémon from 4/19 HP (~21% HP) down to 0, bypassing the red HP state and causing the player to lose. This causes the game to crash. These circumstances will occur together about 1.56% of the time:
* The player must choose {{p|Chimchar}} as their starter, and Chimchar's HP must be 19. This will occur if its HP [[IV]] is 11 or lower, a 12/32 chance (37.5%). (Other starter Pokémon cannot have 19 HP or lower.)
* Starly's Attack cannot be only 6 '''or''' Chimchar's Defense cannot be 10 or higher, although this has a 91.6% chance.
** (Either Starly must not have an Attack-reducing [[Nature]], or Chimchar's Defense IV must be 11 or lower, or Chimchar must have a Defense-reducing Nature, for a combined probability of 21/25 + (4/25*12/32) + (80/800*4/25).)
* With these stats, Starly will deal 3 damage 15/16 (93.75%) of the time and 4 damage 1/16 (6.25%) of the time.
* Starly must deal exactly 3 damage five times, and then 4 damage ((15/16)^5*1/16 or ~4.53%). (It may also deal 4 damage at least four times in the battle, though this has a probability of less than 0.01%.)
* For these circumstances to occur 'naturally', the player would have to give the wild Starly at least six turns to attack, and on average twelve. (Any Chimchar will always outspeed any Starly under the battle circumstances.)
