My apologies for starting another GTA IV thread, but this is a pretty specific issue (and, perhaps, it's not even a GTA issue, but an Xbox issue).
As of this morning, I was about ten hours into the game, having played it casually over the last week. I played about an hour more this morning, autosaved after a mission, and then shut down. But wen I fired up my 360 again this afternoon, my latest autosave file was gone, replaced by one from way back at the start of the game.
I've heard of some wonkiness on the PS3 version, but has anyone else had this same experience on the Xbox? Is there a solution for it, or do I really need to go back and play through the game again?
For what's it's worth, I called Rockstar technical support, and though they were open on Sunday, which was a pleasant surprise, they told that no one, either on the PS3 or the Xbox, has called and logged this specific issue, so they have no idea how to help me at this point.
