Due to a bug, bountyhunters apparently also award for other things than pk scalps. This is not intended. Fortunately the mobs log everything so I can deduct the relevant people the qps.
I'd fix the bug, but somehow the game has shut me out from doing mobol, so you'll have to make do with this warning for now.
Ely edit: bug has been fixed and the people who had been awarded for mob scalps have been docked those qps.
