In two instances since the last patch’s fix I have gotten to the boss door of lightless arbor, but am unable to open it. I tried talking to the npc spriggan in the room one time and another time i ignored them.
On one attempt, I tried tping out of the room and back in, which placed me in the boss room, except it was empty. I repeated this loop again, but instead got locked at the town teleporter unable to move.
