One of them was to survive the fire ring for 90 seconds, this worked fine.
Another one of them was called The Battle Ring, and you had to defeat 20 Shado-Pan Trainees. The quest said that we had to walk into the ring to start the fight, but this did not work for anyone by the looks of things.
The last one was not a daily quest, it was part of the progression quests. It was called "The Secrets of Guo-Lai", and it was an event in the Guo-Lai Halls. The quest ends with the player being released from a cage, and the player is then meant to go back to The Golden Pagoda to hand in the quest. Problem is, the quest givers seem to be phased out.
Pllleeeeaaassseeee fix before reset? :)
