When Manually Saving I decided to save over the “Autosave 2” slot, thus creating my manual save…or so I thought.
That was a mistake because when I started a new game, the new game autosaved over my manual save. (The autosave slots cannot be renamed when saving either, they overwrite with each new autosave.)
With this in mind, I feel it would save a lot of people headaches and lost gameplay (5hrs in my case) if saving over the "Autosave " slots wasn’t an option.
