So I am wondering what i can do to make units unable to upgrade... ie swordsman not able to upgrade to maceman... i want to be able to build any unit i want no matter how high up my techs are, and the way the game is vanilla i can only build macemen once i get that high up. how can i change it to be able to build any unit i want? ive added in many unique units for each civ. i also set it to be only in the medieval age. now i just need to figure this problem out, and ill be set! any help would be awesome!
