I say this as ive noticed the following:
Play character A. Manually save.
Play character B. Manually Save
Go back to character A, play for a while... Character B's Manual save is changed into "AUTOSAVE" for character A. I currently have 5 AUTOSAVES active for one character, all in the specific slots where the manual saves were for 2 of my other characters.
Ontop of this.. i have 6, yep...6..."starting saves" , the one where it saves just before character create.
Anyone else noticed this?
