I am attempting to create a new district that has similar bonuses as the Neighborhood district but has the appearance of the City Center without any buildings in it. I think I have everything setup correctly in the Artdefs for Districts and Landmarks, the district shows up for production and places correctly but it never shows up on the map or in strategic view. Hovering over the tile shows that the district is there and the bonuses apply, just no art shows up.
I attached the code I'm testing this with.
