What is happening
The game crash on sturtup

How to reproduce

1. IDK
2. The game crash on sturtup
3. Crash Report with all installed mod

Version: [1.12.2-2.0.17]
Mod pack: [Custom Modpack]

if you want i can give you the forge version

I don't know if the problem is of your mod, i read "Caught exception from QuantumFlux (quantumflux)" and i think the problem is of your mod

Sorry for my bad translation

as soon as I program the modpack i test it

Thank you for reporting this major issue, I should have tested this version (2.0.17) after uploading it.
I made a mistake during building and ended up with a bad .jar. I re-uploaded version 2.0.17 which should now be working. Can you check if this is the case?

Okay, i'm testing now and for the moment the modpack doesn't crash

Great, thank you for your feedback.
