I accidentally attached my tranport pipe system to my blast furnace, and some Aluminum Ingots (TC) found their way into it. The blast furnace turned them into Refined Steel (Quadrum). It isn't listed as a valid recipe, so I gather it is not supposed to do that.
Happened to some of my players as well. We are currently on the latest version of Regrowth 0.8.8. This works for many things like tin, aluminium, copper, osmium, etc.
