It appears I have hit some upper limit on the number of manual saves I can have. Up until a day or so ago, when I hit 'options' and then 'save' I'd get a box that said "NEW SAVE DATA" (or some such) then the option screen to resume, et al. When I do that now, I get returned to a list of saves that ends with one I saved... several days earlier.
Is there any way to clear out old saves to make room for new ones? I haven't found any such option in the settings - but that doesn't mean there isn't one somewhere.
(An aside to the developers ... if there ISN'T, there SHOULD be.)
