Is this mod client side?
Because whenever I try to upload a server file to curse forge it gets rejected because of version 2.0.1 of this mod. Dunno why.

Are you saying that curse rejects the server files? Please elaborate what you mean, screenshots will help

Thats the message if I try to uploade it:

The same file is also in my client package of the modpack and that upload works fine.

This is an issue with curseforge, I haven't deleted any files. I have linked them to this issue though, so hopefully they can figure it out
