Heads up, Pokemon Trainers: according to multiple player reports, a game breaking bug has been found in Pokemon X and Y's Lumiose City.

The problem, which is apparently rendering player's files irreversibly corrupt, seems to occur after saving in the region. Players are reporting on forums that their 3DS became unresponsive after trying to load the save file, and there is no solution other than to delete and start over. You can check out a video of the bug corrupting a player's 3DS below (via Game Informer ). The bug is being reported across both European and Japanese versions of the game.While there has been no official acknowledgement of the bug from Nintendo, it's probably best to avoid saving in Lumiose City... just in case.
