It is not directly the same what is described upwards, I created a own bugreport for this topic, but I posted it here also:

I got this message now for 3 times during playing the game. Unfortunatly always when I was high equipped ^^ but ok...I hope it was just bad luck and no "Char killed because he was alive to long thing"

1.) I was walking up some stairs in the Firefighters Station in "Cernaya Polana" and boom, "My leg hurts, you are dead" But there was for sure nobody else.

2.) I was climbing up the ladder at the mast southeast from "Lesnoy Khrebet", boom the same stuff, as I was on the first floor, black screen....again I was not shot. (Friend of mine was close by..there was nobody else than him, and no he didnt shoot me) He said I was lying on the ground under the mast.

But now! The most strange stuff as I have experienced in this game:

3.) I logged out in the north of the western Airfield at "Bashnya". I logged me in today and I spawned dead....same Message "My leg hurts, you are dead". Here I have to add that I logged out under a tree. Maybe it has something to do with some solid stuff arround you when you log out...When you log in again, you maybe get stuck or it will kick you away from them when u spawn and then you die.

And this logging in and out bug happened to me for 4 times like i described it in point 3.)
So I think this is a serious bug issue.

I think you should avoid logging out without having something solid 5m arround you. It never happned when I was loggin out in a Bush.
