Finally getting in the mood to play Minecraft, I spent pretty much all of Sunday going through my modlist to see what keeps crashing my game, and this mod turned out to be the culprit.
If I add this mod to my game, it crashes before the main menu loads. (As well as before NeoForge even loads the mods. It just sits on the mod loading screen for a bit, then before the usual signs that it works(as-in words popping up in the bottom left corner), it just crashes.)
All I can hope is that the non-snapshot 1.20.1 version will work fine.
