Mob glitch? Undying

Not the first time i have seen this but the voodoo necromancer mob sometimes just won't die. Well, he does die, but then pops right back up with 2 of his undead mobs and then you kill him again and he pops back up and endlessly follows you across the map. and sometimes gets you killed...

i see this only from rare mob 'aura' that raises the minions- you sure it deosn't have a minion tag on it?

I have seen second hand in my brother's maps (and I guess technically first hand when he invited me in to see if maybe I was able to deal with it) one random monster in some kind of an indoor map that was left after the map reported full clear, 0 left (no delirium or expedition btw), that continued following around behaving very much alive and doing damage, but also not responding to any attempts to deal with it (I say it that way because projectiles pass through, minions ignore it, aoe doesn't hit it, etc).

It is a very rare glitch, that my brother and I have encountered exactly once with probably at least 1500 hours accumulated between the two of us, but it does happen.

Not sure if this is the same thing though; it does sound kinda like a reviving minions pack (and let me be the first to tell you, if the first one of those you encounter is a demon shepherd and you don't spot it immediately, its a rough time).

One way or the other, this maybe belongs in bug reports I think? I dunno.
