I'm playing on a Custom Modpack I made for me and my friends, and one of them got a full set of Cloudium armor. But whenever he equips the whole set (including gloves) it kicks him off the server with a simple "Internal Server Error" and I have to go edit his playerfile to delete one of the pieces so he can join back.

Server Console gives this error:

This is a little issue created by the ability check. Only the player has the armor set, and so the server can't actually check the KeyBind of the ability since it's a client job. Very easy fix and you'll see it in the next beta 1.0.5.
