Xbox – Why won’t the game save anymore

portal-2xbox-360

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?

I solved this problem for myself by not signing in until the game had started. Then, I signed in. When I loaded the last save, it went back to the save that I was unable to access before.
