The biolith config doesn't seem to be generating at all on Neoforge 1.21
From what I could tell from: https://github.com/TerraformersMC/Biolith/wiki/Global-Configuration it should generate as a folder in ./config/biolith but I can't see anything or any config files associated with the name.
I also checked the saves folder just incase anything had changed since I know some mods use the /serverconfig folder there.
