Oh, you misunderstand me. For one, having the game auto-save doesn't mean it can't still have manual saving for those paranoid about losing items like that. Secondly, if the auto-saving is clever that doesn't have to happen; just as an example, it could provide loading options such as "Retry battle", "Return to chapter start", "Return to chapter x", in addition to restarting. It doesn't have to be oversimplistic just because it's automatic, it just takes some creative development.
