I have all the Autosave features turned off on my game and have not had a save Corrupt yet.
Agh. I did this, only problem with that is when you finish an intense battle that was too full on to keep hitting quicksave then right as the fight finishes and you go to hit quicksave, CTD! Happens to me way too often.
Using xbox I save often and I can not save on any
In that case, try starting a new game. See if that works? I had to do this when a good portion of the map kept causing crashes due to corruption.
*editedit* I need to learn to read, dammit
