The tech tree lines are so illogical! http://civilization.wikia.com/wiki/File:Tech_Tree_(Civ6).jpg Example offenses: Banking requires Education. Education requires Apprenticeship. So why is there another arrow from Apprenticeship to Banking? Apprenticeship to Gunpowder Economics and Scientific Theory. Why is there a line under Scientific Theory to prerequisites of Scientific Theory? Rifling is misaligned with everything after it Combined Arms, Combustion. Steel. Has any work addressed this?
