Disabled Quests

[Soulfire]

Some time back I noticed a quest marker above Momodi (for Cutthroat Prices). I never took the quest, and rode the airship. Later I heard that she gives you a free pass to do so. Earlier today I checked back, and the quest was gone. Similarly, I had entered Shposhae before starting Call of Booty offered by Hasthwab, and when I went to talk to him he wasn't offering any quests.

This should not happen. For one, I'm missing characterization and story, and two, this is a slap in the face to hardcore completionists; I can't get the achievements in my history on Lodestone or the quest in my quest history now because they've been disabled.

The only condition that should cause a quest to become disabled should be the completion of the quest.

Edit: Seems I had to complete What a Pirate Wants in order to enable Call of Booty. However, that doesn't solve the problem with Momodi.
