The problem in the mission \"the Pit\" (Dying Light)

Hello. The problem is this: In the mission the Pit came to the room with zere. Opened the door, then started the movie. At this point there was a power cut (in the apartment). Thought nothing to worry about.
But no! Downloaded, I in the same location - in front of the door, behind which was zere. No one but me, no more. To get out of this location there is no opportunity, tried every door, etc.
The descriptions of the mission I had to throw in the arena, but nothing happens.
I love it!
