when i load this with the quality mod (and the janky foundry), while the plant itself can be different qualities, the recipes only show base qualities, and any attempt to put quality modules in it, cause all the recipes to disappear. this also happens with the foundry.

edit: looks like it was a mod conflict with something else, with just quality, EM plant, and foundry it all works

Glad you figured it out. Specifically, it is an issue with adding the EM plant and foundry into a world that already has quality enabled

I had the same issue, added the EM plant and foundry after i already started a game. Fixed it by using this command: /c game.player.force.reset_technology_effects()
