Yo,
Sorry for bothering you again but here is this really nasty bug which happens in the ancient city (City after the Catacombs).
When I walk to the big door that is behind the statue and then go all the way to the right, into that one room and back outside again, I get a black screen.
I still hear the foot steps, the music is still playing and the letters in the left upper corner even tell you in which area you are but there is a black screen.
No matter in which direction I leave that room I always get a black screen.
