#5 is still currently a problem even after removing it from the supported list.

I can suggest uploads to Modrinth. Asides from general benefits to users and modmakers, it is much more straightforward, and much quicker, to resolve these kinds of versioning errors.

This issue appears to be finally resolved on updaters.

I'm not going to upload to Modrinth. But someone was able to refresh the cache over at CurseForge.
