Description

When attempting to load a world (currently using ATM10, but should be reproducible with only Improved Mobs AI and Modern Industrialization) the game crashes complaining that an item cannot be repaired (it's an equipement item and I've also tried disabling the whole mod ID with the blacklist).

Apparently, it's something "on their end" that they added in order to check if other mods handle null checks (I'm currently recompiling the code with one of the proposed solutions to check if it works).

The issue thread on their end is the following: AztechMC/Modern-Industrialization#961

EDIT: apparently it also happens with Extended Industrialization (looking at their code, the same workaround).

Steps to reproduce

1. Load Minecraft on NeoForge with the proposed mods (MI and Improved Mobs AI + dependency).
2. Create a world and let it crash before it loads.

Mods that might affect the issue

Modern Industrialization - 2.2.31

EDIT: Extended Inustrialization - 1.10.4-beta
