Bug Report

Observed Behaviour
In trying to give my pickaxe a handle out of leather, the GUI for creating it popped up, highlighting the leather in my inventory. On hovering over the leather, the game crashes with this report.

Expected Behaviour
Less crashing ideally

Minimal setup needed to reproduce

• Forge version: 1.12.2-28.1.90
• Other mods: None
• Tetra configuration: Completely Default

Steps to reproduce
Place a pickaxe (I used Diamond) in the workbench, select Handle -> Craft -> Handle -> Hover over Leather highlighted in inventory

I've not been able to reproduce this issue, but I noticed a bunch of data that did not load properly while attempting to reproduce it. Also found a spot that might have been causing this which I patched up, although I've not been able to verify if it did as cannot get it to crash to begin with.

Feel free to reopen if this issue persists

I was about to come back and update that in a larger modpack (with OptiFine even, of all things!) I couldn't reproduce it either. I'll test to see if it ever happens again, but it very well could've been a loading error causing something else down the line to break ¯\_(ツ)_/¯
