In the final fight to complete the fabled Mystic 1.0, it's not updating after killing the Shade of Sellok. I had to mentor and remove all buffs, blank my AA, remove most gear so that I didn't 1 shot the encounter with some random proc. Burn Sellok down slowly, kill his adds. He vanishes at 25% like he's supposed to. I use the Eye of Thalger to see him, continue the fight and kill him. The quest doesn't update with his death, and I am unable to destroy the altar (no interaction possible with it). I've tried this 5 times now, to no avail. What am I missing? Or is it just broken, preventing me from starting 2.0?
