i lost everything

Its not the game its just something to do with the hard drives this has happened in alot of other games Gears 1,2,3,J, Borderlands 1 and 2 the list goes on, just when you do it just make sure you save it. And see it save also you should do a test on your
hard drive so it can clean out any files that are damaged. If you need help on your game ill help just send a message.

Same thing happened to me after my game froze. Don't get it man I don't understand how the SvM stuff is gone when our rank and all of that shouldn't even be stored on our hard drive.

I downloaded the update and my saved game is lost! Taking it in to Gamestop now.

This happened to us as well, turned the Xbox off for dinner and half the missions completed were gone when we turned it back on.
