Link to crash log: (please use a paste site, do not attach the .txt or paste the log inline)

Steps to reproduce:

1. Keep taking it on and off it will still happen

What I expected to happen: To show how it looks like on a player

What happened instead: The armor wants to become magic armor

ah, the classical "armor stands are dumb" helmet-facing-south and armor-breathing bugs
fix coming
