Additional context
Latvian and Max have created an outreach room on the latvian discord to help addon mods directly make the transition to the new recipe schema system as outlined here, https://wiki.latvian.dev/books/kubejs/page/kubejs-61-update#bkmrk-for-addon-mod-develo
If you would be willing to update to use the new system they will work with you to help iron out any issues you run into. I appreciate the work you've put into this mod and I was looking at it as a replacement for create sifter in one of our upcoming packs.

This has been fixed in 0b3b941
New versions has been uploaded to CurseForge and Modrinth.
