It appears DomesticationInnovation is doing some very dangerous and cursed stuff to modify vanilla pools at game load instead of mod loading.

The issue starts here where you are trying to access config values far too early and Forge crashes the dev environment. Forge is also warning that this will crash prod soon so you ill need to change how you access the config before the breaking change is done

Though I will say this, this mixin needs to go. Please. This is unneeded entirely and will always cause issues and is incompatible with datapacks adding to the pool files

I strongly, strongly recommend following this gist I made for how to add to vanilla villages in a more safe and compatible way.

Please do not hesitate to ask any questions or if you need help with updating to this alternative way of adding to villages which should also solve your config issue as well.

should be fixed in the latest citadel version
