Issue description:
Weird interaction between RFTools (possibly McJtyLib), Botania and Baubles leading to a crash.

Steps to reproduce:

1. Equip "The Spectator" bauble from Botania.
2. Go near an RFTools matter transmitter.
3. Press sneak key (shift).
4. Observe the crash.

Versions:

• Minecraft: 1.12.2
• Platform: Linux x86_64, MultiMC, Oracle JDK 1.8.0_172
• Forge: 2707
• McJtyLib: 3.0.1 (mcjtylib_ng)
• RFTools: 7.52

Possibly incompatible mods and versions: FoamFix (tried with both anarchy and lawful), VanillaFix (which actually caught this crash and identified 3 mods involved).

Crash report and detailed modlist:
crash-2018-06-12_21.56.14-server.txt

Probably caused by 9cecac8

Fixed next release

Additional info: when MMcJtyLib and all dependent mods are downgraded to pre-3.0.0 version (2.6.7 in my case), without touching any other mods, the crash disappears and everything works as intended.
