Clive barkers Undying Bug (door-bug)
I got a bug in this game now a door cant open anymore the sound of the door opening gets clunky and just stops. “Q-manor est.wing.lower”

Not sure I can solve this game now.

I found this walkthrough, but I saw that there are many doors characterized as east wing lower.
See if you can figure out where you are.
