I need help abandoning a main scenario quest. I wish to challenge Tataru to Triple Triad at Camp Dragonhead in the questline prior to 3.0 and I picked up the "Coming to Ishgard" quest. That quest apparently makes her unchallengeable, and I cannot drop the quest itself to reverse the effect.

I submitted two GM tickets: the first was an automated response about the Active Help guide (useless), and the second was that it was out of the scope of GM abilities (also a pregen response). I do need help with the issue.

Please advise.
