I have noticed that playing civ3 after installing the latest official patch that I am no longer able to upgrade units. Case in point: Currently I am playing the Americans (in America of all places). I just made a road that brings iron into Washington, enabling me to build swordsman. However, when I activate my warriors in Washington or bring additional warriors into the town I am unable to upgrade them to swordsman (the command is no longer available). Anyone else having this problem other than me?
