Thanks for that, I will do.

I never really thought of removing old Barbarian buildings. I usually just remove the temples and build new ones but I leave the production buildings to keep a flow of soldiers on the front lines. One of my biggest non-Roman cities is Narbo Martius, currently occupied by my heir. Public order and pop growth is terrible there, pretty much on the edge of a full blown riot. I bet it's those Barbarian buildings that are the problem. Bah.

I'm gonna go demolish the buildings in my three big non-Roman cities and hopefully I can take off from here.
