Unerroot "slay all enemies in the Labrynth of Rot (1 remains).
I was slaying the enemies to open the sealed door in Underroot. I had noticed the red dot still show up saying 1 enemy is still there but nothing around was alive. I exited the dungoen, returned to have the bodies gone but the red dot and “enemy” still alive.
I was using a lot of AoE Druit skills such as Shred, Poison Creeper, and Ravens.
My druid does seem to path around what might be an enemy but when trying to his the spot he paths around with an attack, no damage is done nor can I see an enemy there other than on the mini map.
