Prison of the Planes - disappearing orbs?
On three separate runs now (heroic elite) the power orbs disappear once placed into the receptors, before anything is pulled - the last run took 3 crystals on three separate receptors, until I ran out of any to complete the quest. New bug? :/ (Rather, really old bug back yet again?!)
edit: Ok, the bug seems to be related to artificer dogs - taking them and not triggering the lever, but the game thinking it was triggered. OR else the dog sometimes takes out the orb, because relog results in the orbs being where the dog was. (...)
