A lot of quests seem to be having trouble giving rewards. For example: Hullabaloo's quest didn't give me the headphones, the Aviator quest didn't give me the lantern. Unless these quests have gotten their items removed it should really be looked in to since the items I did the quests for are only available through said quest.
I should have gotten items, preferably the correct ones, when I completed a quest.
To come across this issue all I've done is complete quest dialog fully.
