[Klyka 0]

Name was FreakyMix.

I killed him in Cherno, 2 minutes later he spawned next to his corpse with a weapon and other items.

I killed him again and hid in the room of an apartement building when my character just fell over and died.

Just happened again, same server DE512.

FreakyMix joins the server, suddenly teleports behind my friend and me who were running through the forest.

Kills us both.
