If you do /mercy and shoot when the Soldier's about to kill himself, you
're gonna lose blood with every bullet you shoot afterwards. Looks cool, but i think it's a bug...

leave that bug alone, it's fun to do it :D no harm is done by this bug anyway, so this is one of those bugs that shouldnt be fixed :D

Yup, that's a leftover from a bigger /mercy bug, just keep it :)
