Several people have reported experiencing a massive bug in their copies of Pokémon X and Y. The bug isn’t a Weedle or even a Spewpa, but rather a potentially game-breaking glitch that is triggered when a player loads a file saved in Lumiose City.

Different videos seem to demonstrate the same problem in both European and Japanese copies of the game, suggesting that the glitch isn’t limited to a particular region-locked version.
