Thought i'd start off the Eternal chain quest on some alts just to check steps and am again stuck at "Hell from the Heavens" stage where Arbritus the Tuath'De Commander is not spawning.

I noticed his spawn point was moved a bit to the 'right' and the tent where you do the next step to collect the weapon was also moved to the right but shard hopping makes no difference, no sign of Arbritus.
