It was within ten Minutes, Took me about 3 to get back to my dead body

The body should disappear after ten minutes in the current version of the game.
As you can't loot and it disappears after relog, it seems the body is correctly removed server-side, but the client does not remove it (unless you relog).

Were you still within these ten minutes or over?

confirmed

Confirmed. Added two screenshots. I tried various approaches in first and third person for several minutes before giving up. I also tried using the vicinity tab but for whatever reason I did not have the presence of mind to take a screenshot of that.

somebody hid your body maybe? there was a bug where when you hid a body the body persists for a while but unlootable

Confirmed: Happened to me also. Body was visible but could not be interacted with.

This is still happening. I briefly got the option to click the scroll wheel, but had to move as there were zombies. After clear, body remained couldn't do anything to it. Re-log made it disappear.

Confirmed. It was within time as well, as I was able to have a friend loot my corpse when I could not.

Confirmed,happened to me too.

As far as I experienced, the bug is that you can see your body and not that you cant loot it! To clearify, when I played with my mates it often happens that one of us said 'my body is still there but i cant loot it'. But in (i think) all cases it was only visible for the owner of the dead body. The rest of the group couldnt see it. So it probably disappeared after the 10 min or somebody hided it. --> It is correct that you cant loot it, but you shouldnt see it ;-)

What Justus says is true. The body is actually not there. The fact that you see it is actually a bug. We need to find a guaranteed way to reproduce the problem to do anything about it however.
