Possible Game Breaking Bug - Pokemon Y

Saving in Lumiose City and then reloading has caused several problems for people according to the internet. The only fix for this is to completely restart a new game. The bug makes textures not pop in, some art doesn't show up on the screen and at worse the game freezes completely. Best thing to do is NOT save in this town, period. If you have to, do your best to not turn off the game or this problem could occur for you too.
