Steps:

1- Disconnected during a cutscene for the Windhurst mission "Moon Reading"
2- Logged back on to find that the cutscene would not trigger again.

4-attempted to abandon the mission.
5-attempted to change allegiance to a different nation.
6-Spoke to NPCs whose dialogue changes based on your status with the mission, such as Kupipi in Heaven's Tower. Her dialogue suggested that I had already completed the mission, as she referred to me as being rank 10.
7-opened an in game ticket and was advised to make a post on the forums regarding the issue.
8-At the time I had become frustrated with the whole ordeal and stepped away from Final Fantasy XI for a while.
9-July 3rd I reactivated my account and attempted the same steps as before, retracing my steps through the mission, to no avail.
10-Made a post on the forums, it was marked as inadequate information.
11-called the customer service number for advise on how I should proceed.
12-based on said advise, I'm now reposting in hopes of getting this issue resolved.
