I just did a dungeon run in the oasis, and it was great fun.. I had to get the quest unjust desert to enter and that was ok... after we want to do another run, but discover that we can't enter...

We can't get no follow up quest, so my question is.. whats up wit that.. can you only do that dungeon 1 time? or is it on some kind of timer, so you can only do it once a day, or?
