So I stayed up playing Gears of War 3 all night, I got tired and went to sleep eventually. I woke up and turned on my 360 to discover that all my saves are gone, along with my gamerscore. All the games I downloaded are still in my library, I had about 13000 gamerscore and when I logged into this forum It showed my gamerscore as it was before what happened. I'm extremely confused about this and i do not have a clue what to do about this, and suggestions would be extremely appreciated. Has this happened to anyone else.
