My save function on single player seems to be completely gone.
I played for a while yesterday, yet when I opened the game today all my progress was lost and I was right back to where I started yesterday.
I have tried restarting. I have also advanced farther and saved the game again, yet when I exit the game and come back I always return to the same starting point, it never marks or saves my progress.
Is this a problem with the game or with the xbox 360?
