May be a similar bug to http://forums.warchest.com/showthread.php/36291-A-kill-given-after-map-end-if-a-player-disconnects
May also be a feature attempting to punish selfkilling in-fight (though I don’t think so)?
This seems to work if one suicides right after he killed someone and got some damage from him. I have not checked if this gives him a frag in the scores, but you can at least see this in the obituaries section:
Sometimes an “X” is shown as a “weapon” of kill, sometimes a weapon the victim was carrying is shown as the weapon of kill.
thx to redtractor for testing this.
