On my current playthrough I have two saves, one autosave and a normal save, every time I try to load either one it tells me "This game requires downloadable content that is not available" when I know for sure that I havn't deleted it. If I select load anyway it tells me "the storage device you are using is no longer available" and sends me back to the main menu. Now I've had to restart my game once due to save files not loading and don't wanna have to do it again, is there any way to fix this without starting the whole thing from scratch?
I have experienced this bug, however I cycle 3-4 saves for each playthrough, I was able to reload one of the other saves and play again normally.
For that matter, that's a tip I'd give ANYONE playing this game, cycle multiple saves for each playthrough, 3+ should be good, when you save, overwrite the oldest one. Simply relying on one save and the AUTO is basically suicide. Auto saves are the work of the devil.
