One of the first things I did when I started playing was buying 2 vanity helms. The squid and classic ones. When I hit lvl 20 I went and bought all the lvl 20 plat gear. When I highlighted the helm(and all other non vanity helms) I could see them on my char in the menu. But once I press equip they dissapear. I get the stat bonuses but no helm shows after equipped neither in menu nor in game. I can see all vanities but not non vanity. It's not a game breaking issue just kinda weird.
