Factorio 0.17.79
Madclown's Processing 1.3.6
Angel's Smelting 0.5.7 / Angel's Refining 0.10.14
Setting up a Titanium Ingot setup using the Madclown-added alternate recipe (6x Magnesium Ingot + 8x Titanium Pellet => 24x Titanium Ingot + 6x Magnesium Ore) results in a rather hilarious doubling of the Magnesium consumed by the recipe, at the cost of a tiny bit of Coal and Hydrochloric Acid
(I originally started looking at this when I saw that the MadClown recipe could be looped with the regular Titanium recipe, by feeding Calcium Chloride and Limestone back and forth. While I like that feature... It's probably also another balance issue that in order to match CaCl / Limestone inputs and outputs, the MadClown recipe needs to be running at 13x the rate of the Angel's recipe. That also could use toning down.)
Screenshot of the setup, displayed by Helmod, which demonstrates both issues. Key points are the 2.77 Magnesium excess output (the duplication), and the 7.7% rate which the top recipe runs at (the 13x rate issue).
