You updated for 1.18 on Curseforge, but not 1.18.1?

I have just verified that the version up on CurseForge for 1.18 is compatiable with 1.18.1
So I have marked it as a 1.18.1 version also, this fixes this issue.

If at some point that version does not work for 1.18.x, then I will upload af new version 😄
