Figured I'd post it here as the thread relates, but in K2 Spaced Out, Lead replaces the default asteroid crushing and makes it so you cannot get space science without sending up rockets of iron to get enough science to get the alternative metallic asteroid crushing. I am unsure if it is intended, however a suggestion I'll make is to swap the recipes, so that you get iron first instead of lead, or to change the amounts so that the original recipe still gives iron and the alternative would give more or favor the secondary product (in this case, lead).
Lead also only makes pistol ammo, which would be useless in space regardless, so the change would be welcome, though again my apologies if I am missing something here.
Thank you and have a great day!
