I found a very roundabout way of doing it. But it still requires Blizzard’s attention to make it so it doesn’t require such methods to circumvent their systems. Since this happened to a friend and I recreated the problem. What I did is after I got too the temple, I flew as fast as I can to get too Howling Fjord. Soon as I got in zone, I dismount and fell to my death. So it can force spawn me too nearest grave yard in the zone. I don’t know if it restarted the timer for returning you. But I didn’t risk it to find out. Then I mounted up and flew as fast as possible too quest area from graveyard. It worked out and my friend was about to do the quest. Hopefully this helps.
