[quote][b]Posted by:[/b] Mythical Wolf Not a glitch or bug. You turned off your Xbox while it saving. They warned you not to do so and since you did it anyway, you deserve to have all your campaign data removed. Run through the game on easy to unlock all the missions again. [/quote] I'm pretty sure I've told you this before, but I'll try again. No, that is not the only way it happens. It has happened to me on four separate occasions. I have never turned the game off while it was loading. Every time I get off, I'm sitting in the menu literally doing nothing. When it happened to me, it seemed to coincide with an update. Now whether that's my Xbox, the hard drive, or the game itself, I cannot say. What I can say is that all four of these occurrences had nothing to do with anything I did or did not do. It might be my Xbox or my hard drive because the same thing recently happened with Resident Evil 6. [Edited on 11.15.2012 4:23 PM PST]
