There seems to be a problem transferring saves from 0.3 to 0.4.1, where if you had a character's profile set to display an unlocked outfit, you get a list index out of range exception whenever you try to open their profile.
EDIT: In fact, it seems all unlocked outfits have been reverted.
Your outfit handling seems to work by appending them to the list upon unlock, rather than using variables to check whether they are unlocked. Their addition to the lists in this way seems to not be persisted in the savefiles.
