About this Mod

This project fixed the not sifting problem in original project's 1.21.4 version.

This project brings the backported 1.21.1 version from 1.21.4 version. So now you're able to play with ExNihilo: Sequentia under MC 1.21.1.

I don't guarantee any future updates so this will be kind of archived project.
