Playing voidblock without any other mods, if I want to use the void electric engine crafting step it creates barrels of lubricant. Since barrels aren't used up, they essentially become an unvoidable byproduct which I need to store forever. I imagine that its intended that the quality mod is used to recycle them, but I think its not great that its required just to use the recipe for a prolonged period. I think it would be a good idea to either change the product in the recipe from barrels of lubricant to just lubricant, or add some way to get rid of barrels into the mod itself.
