I'm sick of dying to Stupulag because the fire AOE goes through buildings, and there is nothing that you can do to stop it.
My only deaths from farming the acorns come due to this. Any time that anyone engages the event and cannot kill the mob quickly, this mechanism will happen and we will die, even if we're up the stairs, about to go towards the inside of the building or if we're passing the first arch of mobs to go into the ''courtyard'' side where Stupulag is.
