Disguise Error

Mythic Mobs Build 1754
Libs Disguises 9.09
MythicLIB 1.01
Spigot 1.10.2

I am getting this error - http://pastebin.com/Xkqtzrbx

This is when I try and spawn my mob called the Leaper.
Mob file - http://pastebin.com/V0Qagzgt

In-game it says an internal error occurred.

This mob used to work with LibsDisguses 9.0.7 and the release version of Mythic Mobs 2.5.0.
