Playing with a friend, he was far south and I north east.
He hears shooting, while alone inside a house, character starts moaning and then he is unconscious and dies.
At the same time I was trying to drown my character to spawn further south. While under water I hear shooting too. So I stand up out of the water. My character moans twice. Screen flashing black / white and then he dies.
I respawn and the server goes down 10 seconds later.

WTF?
