It doesn't accept osmium compressors as a valid block.

fixed it by changing all the "extendedcrafting:compressor@2" lines in largemicroverse.json to "extendedcrafting:compressor"

Thank you! I wasn't able to build the Large Microverse Projector until I made this change as only some of the Quantum Compressors were being recognised as correct. Making this change to large_microverse.json worked perfectly

This is a known bug indeed. If it can be fixed this easy, it's wonderful.

Looks like it works indeed.
