After new patch killed corpses are disappearing after few seconds.
- Legacy ID
- Kill someone.
- Wait. (I think it's caused by clicking "respawn" button after dead.)
I think, if killed guy respawns (by the option in menu) corps disappearing won't happen, but if he leaves the server (and no matter if he does or doesn't re-log in) the corps will disappear. Didn't try either ways but saw how just killed (by me) corpses immediately disappeared.
