I never noticed this before but now apparently activating ambush turns your hair and uniform black. It's a neet effect, but incomplete on the uniforms. There's always one shoulder/arm color patch that goes unchanged. On some uniform combinations this ends up looking terrible, since you suddenly end up looking like a floating pair of arms or shoulders in the middle of combat. Either go all the way and turn every uniform area black, or preferably revert things to the way they were. Players paid good money for c-store uniforms to make their toons look the way they want. Power graphics effects shouldn't get in the way of that.
