Issue description: Crash when opening environmental controller

Steps to reproduce: Not sure, I opened my environmental controller and it crashed. I am on a server.

Versions:

• Minecraft: 1.12.2
• Forge: 8.0.99.99
• McJtyLib: 1.12.2-3.0.0
• RFTools: 1.12.2-7.50

Possibly incompatible mods and versions: Using SpongeForge

Relevant logs, if any: https://gist.github.com/Habeeb-M/5e51ba643b3e7b1a74ffc9069b78d225

Your McJtyLib and RFTools versions are both outdated. See if it still happens when you update.

I'll have to ask the server owner to update.

Any update on this? Also, assuming it still crashes for you, can you try this build and post the crash log it gives? mcjtylib-1.12-3.0.2+f2de7c9.zip

The server had a recent , so I can't test right now. If the issue pops up again, I'll reopen this.
