Strange Days In N.Italy

[HopAlongBunny]

I'm playing a Roman campaign. Captured and built typeI governance buildings in both; the regions are up to "great walls", highest available gov't building and I cannot build any MIC structure above the base Levy building.

I know both regions are capable of building regular "homeland" structures because I was churning out legions from them in a previous campaign. Any thoughts on whats up with this campaign?

edit: I should note both were enslaved on capture if that makes any difference.
