TL;DR
Reorder the science pack tiers to match the order in which they're obtained during normal gameplay.What ?
At present moment, military science packs become accessible long before production and blue science. However the game considers the military science "tier" to be above not just blue, but production as well. This results in techs that require blue/production science being higher in the tech list than pure military techs, which is kinda annoying and counter-intuitive.So the suggestion is to change the science pack tiering to:
Red - Green - Military - Blue - Production - High - Space.
