[1.20.1] Crash With Immersive Engineering

[Mike-U5]

Versions:

• Minecraft: 20.1
• NeoForge: 47.1.84
• IguanaTweaks Reborn: 3.0.4
• InsaneLib: 1.12.1

What Happens:
The game crashes when I change any config option. (Presumably, I did not try with every single option but I tried several random ones and it crashes)

Did you report this to Immersive Engineering too? There's nowhere in the crashlog mentioning ITR

I was experiencing this issue a little while ago. ITR certainly has something to do with it.

Deleting your IguanaTweaksReborn configs seems to work. It might be related to specific config options because after resetting my config, I've modified a fair number of things and no longer get the crash.

@Insane96 I have opened an issue on the IE github too. But it is as @CraftyZombie says, it seems to happen with specific configuration options of ITR. Can't quite pin down which.

[Insane96]

I have no idea what might be causing this.

I'm experiencing the exact same error. The error only appears if Immersive Engineering is loaded, and if I disable ANY of the Data Pack mod settings that change recipes etc. So if I turn off "Hardcore Torches", the game crashes when trying to load a world. I can modify other settings, it's just the Data Packs that make the game explode when trying to load a world.

I'm going to go play with the config file for Immersive Engineering. Curious if there's something I can change there that will let me disable data packs. I'm guessing it has something to do with a recipe?

EDIT: Looking at the log file, the crash report mentions something about arc furnace recycling. I scanned through the IE config file, and saw this:

	#The recycling functionality of the arc furnace is no longer controlled by a config option.
	#Like all IE recipes, this is now controlled via a datapack, using the recipe file:
	#immersiveengineering/recipes/arc_recycling_list.json

I'm no minecraft modder, but I'm guessing something isn't playing nicely here with the arc furnace recycling data pack.

What's in that json?

[NotTohm]

same but its when i disable the nether roof

[Insane96]

So you disable only the Nether Roof data pack and the game crashes with IE?

[NotTohm]

yep

[Insane96]

I have no clue why a data pack that changes the Nether dimension could crash IE

[Insane96]

Does this still happen?
