The display bit is fine, just the normal thing of getting question-marks instead of the buildings when you double-click an ai city when you don't have a spy close.

The code is below. As you can see i am using all cultures.

Code:
wooden_pallisade requires factions { barbarian, steppe, carthaginian, eastern, egyptian, greek, roman, } and building_present_min_level government_types govtype4 or building_present_min_level barbgovs barbgov4 or building_present_min_level nomadsett smallstlmnt

            {
                wall_level 0
                tower_level 1
            }

            {
                wooden_wall
            }
        }
I'd normally expect an instant ctd when the game tries to display an info scroll to be related to a text error somewhere but doesn't seem to be. Plus that would normally (i think) show up the same way when you right-clicked a building in one of your own cities. If I start as one of the steppe culture factions and look at a port/wall in one of my starting cities it is fine but not if i start as another faction and then double-click the same city. Strange.

Just wondered if anyone had seen it. I'll try making copies of the port/wall graphics and renaming them steppe instead of the barb ones the culture file is pointing at.

Ty both for comments.
