My partner and i keep getting an error whenever we try to load the game with this mod. Weve both played worlds with it previously so we know it works, but i think the most recent update messed something up. Were using neoforge 1.21.1, tried to make a new game with just this mod and its required tools and it still doesnt work.

Here is the whole error code when loading the game with just this mod and its required mods.
