Steps to reproduce:

1. Have RFTools and Nuclearcraft installed.
2. Place ItemFilter from RFTools.
3. Crash.

Versions:

• Minecraft: 1.12.2
• Forge: 14.23.5.2838

I have posted a similar bug report at Nuclearcraft's issue tracker as well: tomdodd4598/NuclearCraft#553 (I don't know how to properly reference issues through this tracker on other mods)

2. Place ItemFilter from RFTools.

Place it where?

It was just placed anywhere in the world.

This is a bug on my side probs - will get it sorted soon when I'm home!

Soz, forgot to come back here to say that this has been fixed :)
