Bramble Roas don't die!

I was playing in steaming springs map, and for some reason a group of Bramble Roas just wouldn't die - once I expleted their HP, they kept coming back in full health

bump. this has happened to me with bramble rhoas in another map as well...is there some bad coding that prevents these critters from dying or what ? they come in packs, don't have any regen mods, and yet when their HP is depleted somehow come back to full live.,,lol


To add - I don't see any bramble rhoa or any other monster in the vicinity that can 'revive' these minions because when i manage to isolate them they still revive.

Just happened to me on PC.
