Inverted Quality


Inverts the Quality system to negative tiers (positive tiers are removed). Crafting items has a two-thirds chance to reduce their quality by one tier. Items in the lowest tier are nonfunctional. The new Downgrade Port allows high-quality items to be used in low-quality recipes, and the Meltdown Facility allows the melting down of low-quality items back into Normal base materials. Map sliders for higher resources are recommended.

FYI Factorio 2.1 seems to add API changes that lets quality levels be lost on crafts with negative quality modifyers.
