I have noticed a major flaw with this pack. you need duralumin to get kicalk (to get zinc) but you need circuits to make the things to get kicalk. you need zinc to get circuits. not everyone is lucky enough to get a zinc ore patch close enough to even think about mining. either the kicalk plantations or whatever they are called needs the duralumin requirement removed because the smelter to make it needs circuits, or the smelter needs the circuit requirement removed. loving this mod a lot, but its very badly balanced.
