Try Documents-> My Games-> Oblivion-> Saves You should have an autosave.bak Cut that to desktop, back-up the autosave to another directory, rename the autosave.bak to autosave.ess and replace into your save folder. See if you can't load that.
@OP The same trick can be done for quicksave.bak if you haven't already written over it. quicksave.bak is always the second last quicksave you made and quicksave.ess is the last quicksave you made.
re saves V quicksaves .... having just done one of each simultaniously from a new game - they come out at the same size, so my guess is the only thing that's different is that you only have to press one key to perform a quicksave
have you got any reason for believing they're different Pseron - can't imagine why anyone would program them to be
Take it or leave it, Pseron is giving you some good advice. Any Oblivion veteran or long time BGS gamer knows to backup their saves when it comes to Bethesda games. I usually keep 3 saves (quicksave, savefile1 & savefile2 - which are full saves) which has done me fairly well. And then like Tmar, I go an backup those saves to another folder every once in a while.
Best practices programming doesn't guarantee that some people don't screw up once in a while, just reduces the amount of screw ups (just google Oblivion's A-bomb & vampire face aging glitches for PC and vampire cure quest glitch for the PS3 ) . I too think that quicksave is a streamlined save option and doesn't do it as thoroughly as full save. If quicksave used the exact same lines of code that full save did, then it wouldn't be
quicksave, plus it's not guaranteed that the programmers didn't do a minor goof up on file I/O streams with regard to quicksave.
