We had a server reset. Everyone had been kicked of the server, wile we had been on a street. 3 People.

When we joined again. I got my screen changed from "black to world" and saw how my buddys character had been attacked by a zombie. We were on skype and he told me his screen is still black (loading screen). Straight afterwards he had vision and died. His log (lower left corner) was full of messages that he would be bleeding and stuff.
-> blackscreen, death.
