So I tried to make a Client Side Modpack that adds nothing new, and i wanted to add AppleSkin, But it got rejected. Here is the Rejection Message:

I Checked and saw that AppleSkin is marked as Required, Despite mostly working when only on the client. I will be Removing AppleSkin for now, But if this gets fixed ill re-add it.

Changed server-side to "Optional"

Let me know if that'll work for you.

Thanks! I Resumitted my Modpack, I just need to wait for it to be either Approved or Rejected. You Saved me a few hours, as I haven't made another version of it without AppleSkin and i can't use my PC Right now.
