I have multiple USB backups, and the cloud sometimes helps but that could just as easily overwrite a good save with a bad one. Its gotten to the point where every save I make is corrupt, whether it's an autosave or a manual save, and even if I exit the game manually instead of crashing.
Here's the kicker. While I'm in the game, if I quicksave, I can load the quicksave and it will work. But if I exit and reload the game, it tells me that the save I just quickloaded while in the game is actually corrupt. Its pretty ridiculous.
