When a wave ends and I fall down to the next room, my screen turns completely black. The only thing I see is the name plates of the other players. It seems I can still move around. This doesn't happen after every wave, but about 30 % of the time. The only way to get rid of the black screen after it happens, seems to be to leave the server and rejoin. But often the server is then full because someone else already joined the second I left. Or if I don't leave I eventually get kicked of course, since I can't do any damage to what I can't see. I have been playing Killing Floor 2 for over a year and this is the first time I have encountered this issue.
