Issue Description:

Game crashes with JER installed. Crash-report: http://pastebin.com/8fzNLmeF. Log: http://pastebin.com/LPXma9ss

Affected Versions (Do not use "latest"):

• Pokecube Core: 4.4.9
• Pokecube Revival (if applicable): 4.3.9
• Pokecube Mobs (if applicable): 2.2.2
• Minecraft: 1.10.2
• Forge: 1.10.2-12.18.1.2071

for now, don't use the alpha build of JER, use the release or beta build, version 1.10.2-0.4.8.48 is the one I am compatible with.

This issue should be fixed now, JER added back in the needed method for its api.
