Here, I think this has something to do with it adding enderite but not having any way to obtain or define it.

Nevermind. My modpack has a toooon of other errors cropping up now, there's a good chance that this is just a side effect.

People are also commenting that on CurseForge, so don't worry. I'll fix that

Oh! Checking the code, it's because I'm calling a client-only method, I think. That's why it doesn't work on server. I don't have time today, so I'll fix it tomorrow.
