The research for the atomic bomb is still red(unresearchable) even though all requisite techs are researched. I even went so far as to employ a research queue mod (one that even queues missing requisites) to try and figure it out and nothing. I don't know. Is there a hidden tech, is something not being referenced properly, is there something in config? Because I am now generating 80% rich Uranium for creating nuclear artillery shells only to be clotheslined by this
