The mod "Quality Processing" adds new recipes for every item in the game for quality upcycling using a recipe.
These recipes input and output the same science pack + plus some resources as a cost for increasing cost of the item. You can use these recipes for in Igrys Science enhancer machine, effectively adding productivity to these recipes that has science packs in the input and output. This creates max quality infinite science packs with almost no cost, removing the whole game out of the game.

Some solutions could be removing the recipe from the machine if the original recipe doesn't allow productivity, or block recipes that take a science pack as input + output
