Just Deserts main quest bugged

When talking to the quest NPC for quest Just Deserts, I am frozen and unable to move.

NPC: Sozai Rarzai
Quest: Just Deserts
Zone: Middle La Noscea/The Descent

Error: A system error occured during event movement. Followed by a freeze.

Temporary solution: alt-f4 to close the game, enjoy the queue.

Yip, same problem for me and my wife on her account.

Getting exactly the same error here.

Its has been 12 hours and they have done maintenance on the worlds and still the issue persists. Please address, I cannot get into dungeons without doing main story line quests.
