One of my players discovered this oversight. The console throws no errors and the server is 1.13.1.

Normally when trying to equip armor the plugin first checks if the player has any hidden armor. If they do then the plugin unhides the armor for the player. However this does not happen when trying to equip a Elytra or Dragon Head. Those items are equipped while the hidden armor stays hidden. The problem occurs when the hidden armor becomes unhidden. As the plugin takes the hidden armor and equips it to the character. Overwriting the Elytra and Dragon Head they had on.
