The patch seems to fixed it. I also found the way to survive the Bucheum puzzle by throwing an alcohol bottle at the demon. Though am I supposed to get a piece of picture even when I fail to do so and die instead? Because I have found that if I throw wine bottle to wrong box at NAX-05 puzzle, I die and don´t get any part of picture there until I solve the puzzle right.
I encountered another small bug though (unless it´s a feature instead) and that is that one of these purple killers spawned near dance floor and I ran into it while holding wine bottle in my hand. It attacked me, but didn´t kill me. I lost that wine bottle though, which dissapeared. But that killer then kept running in into some object at dancefloor infinitely.
