So, I was on M6 but did alot of mp and now my information is all gone except for my team. 0/1000 ninja ropes. M1. Anyone else have this happen to them. I took my harddrive off and put it on my roommates and after that all my info is gone. 

Yeah, this is a known bug with the game.  It's a damn shame that something like this made it into the final version.  Until it's fixed, people need to only play this on the console they buy it for.

Thanks for letting me know so you think if I just keep playing on my own console I'll be ok? That's a damn shame I have lived with my roommates for the past 7 months and today was the first time I decided to play in the living room on my couch and that happened. What a shame.
