HDB Heads bug

The heads from the Head Database are broken. The command and everything works fine and placing them in your inventory has no problems, but the real problem starts when you open your inventory. When any HDB heads are in your inventory when you open it up, they all turn into Steve heads. This problem happens regardless of server and regardless of player. On rare occasions some heads may actually stay when the inventory is open, but will disappear when placed in a different inventory spot. The only heads that don't disappear are ones that were obtained through /head.
