After hours of doing the event in all three nations, I have practically every event item except for the Horror Head II. I received a Pumpkinhead II and wore only that, just as many posts have suggested, but instead of getting the Horror Head II, I keep getting offered the Trick Staff II over and over again (even though I can't accept it). No matter what I've tried or where I've tried it, I just can't seem to get the Horror Head II. Is it just me, or is this some kind of glitch?
FYI: No event items are stored with the event item NPC. All event items have been in my inventory.
