I had this problem too, but was able to fix it by logging off all the way for 15 minutes and logging back in. It put me right outside the temple. The quest was at the point where you follow Ukaezai to watch the scene of her getting her body back. This took me 3 times of logging on and off (I only did the 15 minute wait the last time) for it to work. And I always did my log offs in the battle room (don't know if that makes a difference or not).
