Can't get draft to work -- late game

[jkp1187]

Perhaps not a 'bug' technically, but definitely a weird logic situation that maybe should be addressed in a future patch (or in Civ 4: Conquests, or whatever expansion pack #3 is called.)

I have managed to get myself into a situation in the industrial era where no 'draftable' units can be built. I researched rocketry before other industrial techs, and now can build Grenadiers, SAM Infantry, Cavalry, and Artillery. As a result, when I swtiched to Nationhood, I cannot draft any units in any city.

See Iustus' explanation for this in the Better AI subforum:
