After you kill Grimak Nailbiter (perhaps too quickly, as I kill him before he goes through all the phases), the final instance chest becomes available to complete the quest and leave. However, when I go to the chest to take rewards, the rewards will not go into my inventory. The exit for the dungeon also is not available until after the rewards are taken. Whether by amount of time to wait or by repetition of opening the chest to take rewards, I will finally get the rewards and then able to exit as a completed instance. Also, as I go to the chest to retake rewards, the rewards are changing. So, this bug is both bad in possibly preventing a completed instance and maybe abused to get more gold crescents or whatever from the chest. There were an inordinate amount of players lined up at the entrance to Gnarlroot (which seems odd).
In any case, the final chest is bugged where it will not give rewards on first opening. Please fix!
