Is this mod compatible with 1.16.4? It appears to not be available to add to 1.16.4 packs in the various launchers that use CurseForge.

Flagged for 1.16.4 on CF, just an oversight.
Forge 1.16.4-35.0.5 makes mods that specify they work with 1.16.3 work with 1.16.4, so i never saw the need to upload a new version yet.
