Intro:

I have been tweaking and adding extra mods to the FTB Revelation pack, and i have encountered and error with Crafttweaker that I am unable to resolve on my own.

Issue Description:

MC Launcher goes through the loading/initialization process, sometime during this process the launcher crashes and nothing happens. Crash report says Crafttweaker errored.

What happens:

I launch the MC client, then part-way through the initialization of the mods, the launcher closes, nothing happens. I checked the crash report, it says Crafttweaker errored during the launch. Not sure why, cant figure out why, came here for people who know more about it.
I tried versions 4.1.9, 4.1.8, 4.1.7, and 4.1.6. Result did not change between those versions.
