One instance, i was killed by a zombie, had the message "you are dead" logged off, and appeared in the location where I died, still bleeding but fine none-the-less.
second instance was my friend had a firefight, both shot at eachother and both had "died" [i was spectating the encounter] , friend logged off then came back alive and unharmed same location and gear. "Victim" didn't repeat the effect.
Body of my friend also disappeared when he logged off.
