7 years ago The reload itself usually fixes this. happens on occaision.
Can confirm working with mage, pally, Warlock & Demonhunter.
but again can pop up randomly and need a reload to solve.
Will try and grab the error next time it comes up, last time iirc it was AngryWorldQuests related for me
It seems like Might of Dalaran button on World map is broken, you need to disable add-on to finish World quests with this ability.
