Hi Cackling Fiend,
I am running a non space-age game with most of your adaptions of the BZmods (aluminium, titanium, tin, lead, natural gas, tungsten) alongside with Ashier's adaptions of the intermediate mods from Planetfall.
My problem is I have no power poles available when entering the steam power age. It seems the alumium mod altered the power pole recipe, so I think there is the problem.
Steam power research, triggered by crafting iron plates, unlocks steam boiler, engine and electric lab, but no power poles. Power poles are locked behind Electronics1 which is also a trigger tech and triggers by crafting copper plates. But copper plates are locked behind copper processing, which in turn requires red science. As my labs require power I cannot research copper processing.
I think it is easily fixed with moving the power pole to the Steam power tech instead of Electronics1.
