actually the boss name is kinda like a bug cause i remember back when i was farming Paragon protectors, during the bug issue with bosses being named boss name and the the mission would be filled with only one kind of bady, example Paragon Protectors, just them no other crey were in the mission.
if you look at the screenie one of the zombies corspe is on the ground and has the same name as one standing up. Aka one died and he rezzed it before its body disapeared.
