Multimixer - Material cost/Profit wrong?


I had an solution for a cure that involves to mix 3 different raw materials to get rid of all side effects.
But it seems the multimixer is not adding the material cost - it takes the costs from the base material. It still means you pay for 3 but for the profit it counts only the costs of the last base you use. Or is the material cost in the production cost included?


So it seems. There are other kind of miscalculations when using the centrifuge when you trash one of the products.
