Question
I downloaded your chunk loader mod and opened Minecraft it said I needed supermartijn642corelib 1.0.15 so I downloaded that too. But its still asking me for this supermartijn642 1.0.9. I'm not sure if this is just an issue for 1.18.1 Minecraft or I'm still missing something.

I have a core and a config library. It is probably asking you for the config library. https://www.curseforge.com/minecraft/mc-mods/supermartijn642s-config-lib

Btw, CurseForge will show you the dependencies if you click on the file you want to use.
