Please provide me with a copy of your playerprofiles.lsb file and I can see if this reproduces the issue.

I managed to solve this issue. A while back, my game crashed, and when I tried to log back in, the game didn't recognize any of my profiles. Long story short, it took some finagling, profile creation and deletion and moving around of saves to get the game to recognize both my profiles and the saves within. A "dummy" profile folder that I had deleted was still showing up in the profile list, although empty, and seemed to be causing issues with the playerprofiles.lsb file.

Now to see what trouble I can get into!
