I made local brewery achievement and I got the witch hat, but it will not appear in the headwear tab. When I make an emote or the "character is saved" animation, the hat will stay still. Look in the images for more information. Reproduce by achieving Local brewery, press on the achievement, equip hat and play any emote. I have expected that the hat will move with you.
