This issue will be resolved on Friday 6th July 5pm AEST.
You may receive a notification that "There are no quests available in this Kingdom." when selecting "Quests" in Khaziel, even though the quests may be 31/31 complete. You may also be unable to complete the Kingdom Power task to "Complete all the Quests" in the Kingdom Power menu and your Kingdom power level may not go from 0 to 1.
Fixing the problem
Both of these issues will be fixed with the server change over on the 6th of July at 7 AM GMT or 5 pm AEST when the Runepriest class is released. If the server change over or "daily reset" does not fix your game at this time please contact support.
