I've found a bug where my headwear that I've earned from my achievements doesn't show in the headwear menu. I can't see my wolf head from the leader of the pack achievement, my witch doctor mask, and many others. I hope this is just a new feature or something, otherwise I'm kind of worried I might be glitched or that I've been hacked. But if you can't fix this issue, it's okay because I've found a way to skirt around the problem.
