I ran into a bug where I think saving as the witch immediately after switching to her for the first time caused the game to do various weird things, including show both a knight and a witch in town, make me show as a knight but have the witch's character UI element in the corner and be unable to use any attacks at all.
I forgot how I fixed this but eventually I got it fixed.
I understand that the dev may not be fixing bugs anymore, but I feel like I should document this, in case anyone's curious, and you never know if it'll be useful information for a speedrunner.
