The mod's fabric version doesn't have the Fabric and Server Utility categories. Adding it will make it easier for users to find the mod. Phanlash brought this up here.

I didn't find the Fabric category in CurseForge. And this mod is not a server utility, both the client and the server should install the mod to work.

I think to get the Fabric category you have to mark the files as using Fabric in the mod loader part

@1point7point4 @MeowMC Fabric category was removed by CursedForge a few days ago. Just look at other Fabric mods.
