If anyone has info on this please let me know, I tried to load a co-op game and it wouldn't let a friend and i continue where we were and after that when we started the campaign over it started letting me work towards achievements that I had already unlocked. it randomly erased all my work towards the "seriously 2.0" achievement and the "party like its 1999" achievement. My rank online also disappeared form three gold bars to no bars at all. also I just played through campaign with a friend on split screen and at the end he got the friends with benefits achievement and I didn't. Any help or explanation would be appreciated. Thanks.
