My character is randomly dying. I was (at both times) walking around in a secure building. The first time it happened it was on a server with less then 10 people, I was inside a house at the second floor, was moving towards the stairs downstairs (where no other player/zombie was around) when suddenly the black screen with ''you are dead'' on it appears.
Second time around (the character after previous story) I just got on to NE airfield and meanwhile was no one in the server, again, just walking in a building (ground floor this time) and out of nowhere I see the black screen with the death message again.
