Forge: 47.4.2
Origins: 1.20.1-1.10.0.9

I'm not totally sure what the mod incompatibility is, but something is making this pack crash shortly after startup before loading completes. I've attached the latest.log below, any help would be appreciated. Removing Origins removes any issues.

(Worth noting, I did try a pack with just Origins and SWEM Lite since that's a culprit of many crashes and incompatibilities, but it loaded just fine so I don't think it's that.)

Soooo I figured it out, looks like there's some kind of incompatibility with Citadel-Fix. Leaving this up but closing it in case anyone gets this issue in future. Learn from me, future generations. Do not be the fool I was :P
