did you do any of the quest prior to the last patch?
if so, ALL but the MM and trick - or - treat need to be done again. yes EVEN the bakeing one, even tho you have a quest history of it, if you did it before the patch, you have to do it again. it will say "The Hungry Halfling" in quest history, if done before the patch, even tho it says in quest history you did it, you HAVE to do it again. that was my hang up on my mask.
