Description of your suggestion.

Why is there no 1.19.4 version? v1.13.12 for mc 1.19.3 doesn't seem to work on 1.19.4

I have no plans to work on 1.19.4
Out of time reasons I only work on the latest version of my mods.

I can understand that, it's fine though since I moved to 1.20.1 a while ago :)
