I placed bits on a wall and instantly crashed.

Crash log: https://pastebin.com/raw/nNfjEErb

After I placed some bits and my world crashed, I couldn’t access the world anymore, so I had to restore to a backup since my world basically became corrupt.

Minecraft version: 1.12.2
Modpack: All the Mods 3, v. 4.4
Chisels & Bits version: 14.9
MCMultiPart version: 2.3.3

I do have OptiFine.

This looks to be a duplicate of #310 more missing worlds from MCMP

@amadornes any progress on these issues???
