Since it seems that the public beta is the only testing that gets done [or else the in house testing is really incompetent] I can understand some bugs from time to time, However bugs do seem to be an ongoing issue with each and every quest lately. Including repeatables.
The thing that I find really annoying is that the bugs don't get fixed before the quests go to the regular worlds, and they have to wait around for a later update, even when the fix has been applied in beta..
