Could the bug be caused by the fact that the mansion is after the forest? Leading to a "you're not supposed to have this note yet" kind of scenario? I went from version .21 to .23, teleported to mansion, went back into the forest, got the first note, got the second note in the mansion and everything worked well. It doesn't save the progress afaik.
Also biiig biiig missed opportunity, small humanoid enemies should ALWAYS have threesome animations imo, be it goblins or kobolds or whatever you want to call them, they move in herds and it's pretty much granted they try to group up on women as well. Hopefully we'll see it in the future
