Intro:

This is my first time ever posting (sorry I've never used this before), but I've found a bug when trying to use CraftTweaker on version 1.12.2, 4.1.20.589.

Issue Description:

I get a crash notification after Phase 3 of forge where Minecraft just stops working, and the report says it's because of this mod?

What happens:

Well Minecraft just stops, goes black an gives me a crash log.

The game crashed whilst there was a severe problem during mod loading that has caused the game to fail
Error: net.minecraftforge.fml.common.LoaderExceptionModCrash: Caught exception from CraftTweaker2 (crafttweaker)
Exit Code: -1

What you expected to happen:

Minecraft to load so I can play?

Script used:

I don't know what this is asking?

crafttweaker.log file:

Where do I find this?

Not a crafttweaker issue, it looks like you ran out of ram, so give your game more ram.
