FAQ says: Either hold 2 of these cities (Segesta, Mediolanum, Patavium, Bononia) AND 2 of these (Lilibeo, Messana, Syracuse)...

I'm holding Segesta, Bononia, Lilibeo, Messana and Syracuse so far, two turns after the last conquest have passed, nothing happens. It's EB 0.8. Have these conditions been changed? Or maybe I have to build something to launch the reform? (Or maybe all owned cities have to have goverment building built? - Bononian one is still under construction). Thanks in advance.
