I have an issue where if I go into Duskp's room on Dogp's route or at the end of DragonpII's route my screen turns black but I can still open my menu and save, I tried saving into a new file to see what happens and when I load in I'm in the room and can't go anywhere but the next room where I interact with the black crystal and then the game tells me the route isn't done. Even if I load a save to before that point the same thing happens. I tried reinstalling and only transferring my saves and I have the latest patch. Does anyone have any idea what's causing this?
