About the first one, I never encountered this error, I gotta check it ;__; did you enter and exit the room when the timer stopped?
For the second problem I can trace you the paths on the map... I know it isn't gameplay friendly but I think I would help you quicker while working on the new build; Zakhari is always two or three steps behind you, so there is a way to escape. I'm sorry I can't do more atm ;__;
(But I'll make the rooms larger in the next update so the chase won't be so frustrating, all feedback is helpful)
