Hey hey guys, Found this bug last night whilst running the BFE duos (feats yo) on my main. If one kills the MK III boss too quickly (before he gets his wings) you will get all the loot and the duo will "end" but once the conversion is complete (as in he gets his wings) one is not able to defeat him. His heath will be depleted and you will continue to do damage, but he will not die. It is kinda fun. And don't worry, I walked in.
