Now or Never is broken
https://www.wowhead.com/quest=60006/now-or-never
I've tried;
Relogging
Abandoning and redoing the quest
.vip capital and running back to Bastion through Oribos
Nothing is fixing this quest.
Edit-
Completed the quest after abandoning it a total of 4 times and killing all the mobs 4 times >.>
