Has anyone had any luck reverting to non-corruptes saves?
I reverted to an earlier non-corrupted save five hours before at REPCONN, saved several times, and when I rebooted my Xbox almost all the new saves except the earliest are corrupted again.
Try running that good save as the ONLY save on your main storage device and see what happens. (Copy it off to another media first through system settings - memory though and keep it off your machine for safekeeping).
Load only from that file and save only to that file. Make sure autosave is completely disabled.
I am convinced that the game, at certain points when loading (maybe every load), checks flags in the saves and compares them to other flags in other saves. If it compares the flags and doesn't like what it sees, it refuses to load that save. Then it has a domino effect, refusing to load each previous save that was created AFTER the next earliest flag check. If the game can only see one save though... it cannot compare the flag with anything and it will load the game.
I tried a variation http://www.gamesas.com/index.php?/topic/1129296-think-i-may-have-developed-a-work-around-re-save-games/ of this last night and ended up getting through 9 save/load cycles with no problems.
Here's a representation:
1 Save game
2 Save game
3 Save game
4 Save game
5 Load Game - Flag check - ok - game loads
6 Save game
7 Save game
8 save game
9 Load game - flag check bad - will refuse to load saves 6, 7, and 8, but WILL load 1,2,3 and 4.
Along those lines, I am not convinced the saves are actually corrupt IF the flags can be modified/disabled by a patch or something.
On the other hand, I could be off in left field, but I don't think so.
Give it a whirl, if you please.
