Describe the bug
We are playing Modern Skyblock 3. I am trying to automate Quantum Solar Panels using Autocrafters, Electric Furnace, Grinder and Compressor from TechReborn in combination with Vanilla Hoppers.

Steps to Reproduce
I have not figured out the exact reason, but here is what I think could trigger the bug.
Steps to reproduce the behavior:

• Build a system that crafts an Advanced Machine Frame from ingot-ingredients
• Configure Tech Reborn Machines to input/ouput

Screenshots

(I replaced an autocrafter with the crafting table. This seems to have fixed crashing)

Environment (please complete the following information with the version):

• Minecraft: TechReborn-1.12.2-2.20.12.937-universal.jar
• Mod Loader: Forge

Logs
Pastebin the log [e.g. logs/latest.log] and link it below:
crash.log

Additional context
The bug is not reproducible on first attempt but it happens often. Breaking crafters or hoppers around them seems to fix the bug. The server only crashes a while after joining.

This repository includes the latest world and all files to start the server using docker-compose.

1.12 is long dead. no longer supported.
dont expect an update

It is something in Draconic Evolution that breaks autocrafting table.
