I have tried on 2 of my chars and neither can pick up the quest from the goblin commoners to start the Fire Festival quest - “The Spinner of Summer Tales”.
I also can’t pick up the quest to go around touching all the bon fires in the Horde and Alliance capitals.
I have done other quests like the torch throwing, a daily, and the "Incense for the Festival Scorchlings.
Am I missing something or is something broken on my account?
