I have got the Cargo disk quest on NT, but also the cleric quest that takes me to her. When I try to give her the needed item however, she asks if I want to become a gatherer instead, making it impossible to get the cargo disk.
I see what happened, when you stack the greet quest (Where you give the steward the tail) and the cargo disk quest, you only get 5 tails, not the 6 needed to finish the quest.
