Simple Description of What Happened
Forge crashed while initialization of mods.

Forge version: 14.23.808
Twilight Forest version: 3.9.851
Link to crash log: https://paste.dimdev.org/eqapivujez.mccrash

What I expected to happen:
I expected forge to start the modpack normally, initializing mods, etc.

What happened instead:
Forge crashed, giving off an error saying it was "unknown". Because the crash had something to do with The Twilight Forest, I decided to report the error to you.

What I have found strangely:
When I was loading my modpack, with the latest version of Twilight Forest (3.9.851) the modpack crashed, however, if I use a version earlier (3.8.689), it doesn't crash. Considering it was an alpha build, were there any pieces of code that were bugged?
