From what I've played of the game so far, it's great, but I've now ran into a gamebreaking glitch. After you've spoken to the professor in the library and entered the next room, the room gets flooded with imps that you have to kill to able to proceed, but 1 or 2 imps always gets stuck outside the room and I can't kill them and therefore I'm stuck in that room. Has this happened to anyone else?

Also, characters sometimes gets stuck in stairs for me which can break cutscenes.

edit - Forcing V-sync on the game via nvidia-settings fixed the problem

Same problem in library. Turn on the V-Sync really helped.
