Even with "Must use GC's own space metals in recipes" off, many recipes still only accept only GC's own metals, even those that don't come from space.

Specifically, this is the case with metal (e.g. bronze) plates in probably all recipes that use them and with lead in geothermal generator. Probably some other cases too, but those are ones I've found.
