My friend got run over by a V3S tonight. This silly man stud behind the truck and the fellow driving it didn't see him = Nominated for DayZ Darwin Award!
Anyway, we couldn't raid his corpse. Any object could be inspected but not taken. The menu entry for taking was missing and drag&drop didn't work either. After a while I recognized, that I could reload my own gun with the ammunition from the corpse. But the very moment I did this all sound of DayZ went off. Teamspeak worked flawless though. Breaking down ghili components worked too. Those parts lay on the ground after the corpse vanished.
After a logoff sound didn't come back on main screen. I needed to restart the whole game DayZ to get it back. Relogged to the same server afterwards.
Funny thing is, I needed to change my raincoat shortly after and found a Gorka jacket containing the corpse's stuff nearby. (Can't tell if the jacket appeared while changing or was already there.) Again handling was limited, I could regain most of the stuff by opening the tuna tin or splitting the ammunition but couldn't take contents or the jacket itself. Darwin-nominated being back again couldn't see the jacket at all. No other player was present to be asked about visibility.
