New type of module: Rigor modules. Rigor modules increase the probability of a recipe returning its most valuable product.
Mods introducing new content into the game.
Furnaces, assembling machines, production chains.
I have not checked the to see if this is a multi mod issue, but at least as of the most recent update, rigor will, as far as I can tell, only create scrap products
Thanks for reporting! I'll check it out.
Fixed in v1.1.5. I'd managed to delete the Scrappy Industry compatibility code when updating the mod for Factorio 2.1, but it has been restored.
