So there is kind of a problem I have been having. The fact that when I try to install a mod on here they aren't the right version, and even though if you look them up on curseforge and they have the option to download them in the version I am putting my server in, you have to download the specific version the mod version on here is. So I think it would be a good idea to add the ability to change mod versions.
