I was playing in server, with couple of friends, when suddenly i was dead. Got a message that my leg was broken. Asked friends to go and check my body, to throw my gear away, there was no body and no gear.
No other players beside my friends were in the server. I did not hear any shots or did not see any zombies around, i was standing still in front of the jail on south-west part of NWAF. No screenshots required for "you are dead"-message and i am pretty sure i cannot reproduce the incident..
