Elenna, the Gatherer Trainer on NT island is not acknowledging completed quests. I tried several of the quests with the same results. For the "craft XX items" type quests, the quest log updates as it should, the message "Return to the trainer" comes up at the right time, and quest log says to return to trainer as well. For the "Gather 50 items" type quests, it does not matter how many of the items you have gathered, whether they are all in one stack or split into the correct number of items for the quest, she will not acknowledge the quest as completed. When greeting her after completing the quest, the original greeting message pops up as if you never obtained the quest.
