When fighting the Mother’s Judgement boss at the end of the Steadfast Barracks in World Tier III, the Mother’s Judgement boss teleported below the foggy wall that is put up automatically to keep you in the fighting area. I cannot target, attack, damage, or do anything to her, nor can I see her with the exception of the minimap where it shows the boss clearly to the south of me ( and I am standing as far south as I can, without hitting the fog wall).
Basically need to teleport out of the dungeon now and do it all over 
She has been down there for 5+ minutes now, no teleport back. I did try using AOE to kill her (I am a lightning druid so Cataclysm would target her) but she seems to be untargetable.
Bug!!
