Doors not opening in the Residential Area 4 (Black Plague)

[ROT51]

.... just re-reading your message ... are you implying that the visual effects should be temporary? because you mentioned a voice-over and effects, but I have no voice-over and the effects do not stop throughout the level. Maybe that is the problem ... as you are already implying.

That's right! Those effects are just temporary. When you stop hearing voices in the corridor, the visual effects must be stopped at less than 10 seconds. But if not, that sounds like technical problem to me. Hopefully it's not.
