So I've been playing this game and I've enjoyed it despite the grind, but I'm about two weeks in and I think I've found some kind of weird bug where both Fuyou and Karin have just... Disappeared. They aren't having conversations with any other characters in other places, although bizarrely other characters can have cutscenes with them, just showing nothing there with their chatboxes. Does anyone have any ideas what's going on/how to fix it? If I have to delete my save and start over, I'll probably just not even bother.
