Once you have researched an upgraded version of the basic building types, is there any way to go back and build the previous versions?
For example, I've researched up to 'Manufacturing Center', or higher, and I've just conquored a new world that had hardly anything built on it. I would like to get it's manufacturing capibilities up to speed, but the only thing I can build are the huge MC's that would take 30-60 turns to complete.
I would like to be able to begin with factories, and work my way up. If the only solution is to buy the first MC, well, alright. I'll just need to save some extra cash, then.
