Oddly enough, I can't find the options for this mod. I don't think there's any conflicting mods, though I do use OptiFine -- which changes the visual settings screen.

in the config folder.

I'm not sure what you mean?

I know where that is, but I can't change the config options.

I'm opening the config file in Notepad++, but I can't change the options. Even when I open it in something else, like just plain old Notepad, they're unchangeable. This is the file I'm talking about. I see what I'm looking for, but on N++ it's just a "4."

Try deleting it and starting the game again to reload it

Still no options to be found...

the config file does not generate on fabric 1.16.4
running the latest applicable version of simple void world, fabric api, and fabric.
Nothing shows up in mod menu either, theres no links registered for the mod either.
Mod works as expected in world.
