About a half hour ago, it asked me if I'd "like to update Spoutcraft" or something. I hit "Yes" and it updated it and everything, but on any of my worlds (I first noticed it in a world with loads of energy collectors) everything that's not vanilla disappears. It's not actually gone, as I can walk into it and stuff, but I can't right or left click these things and opening my inventory crashes the game. If I screwed something up, tell me please.
