I'd tried the quest 3 times (reloged, droped, etc) and it wouldn't work, then - after my post - i noticed the addition, and change in the position, of a few of the quest NPCs (there's a few mobs there that i frequently kill for a JC daily) so i thought i'd try once more. Low and behold it worked flawlessly, as it's supposed to (which it never did before, was just auto complete for the last 3 lvl 80s i've lvled)
As nothing on my end would would seem to account for the change (and addition) of NPCs, i'm assuming it was a fix.
Anyways, all's well that ends well...
Keep up the good work embers!
