I recorded all following incidents with ShadowPlay and will list the videos, time of occurence, server + ip, our usernames and additional info under the incidents.

• Incident 1:

My mate was doing stuff in our farm base with doors closed and locked.
I was joining the game as well and shortly before I joined my mate died out of nowhere.
A few seconds later I joined and after like 3 seconds in game I died as well.
Our doors where still locked and we were alone in our farm base.

• Incident 2:

I respawned on the same Server and after a few seconds I got damage without reason and got unconscious.
After that I could not run properly so I asked a random player to kill me.

• Incident 3:

The respawn after that seemed normal for about half an hour or so.
I got some stuff to survive and logged out.
After I logged in again I went into a container and closed all doors.
Once again I died without reason.
This time the animation looked like getting shot.

As a result when we came back to our base, both cars and a few wooden crates where gone
and almost all items where dropped on the floor to let them despawn before we reach the base.
(the base is located west of Polesovo in a farm)
