Having an odd problem with one of the missions. For the edit shape Polygon mission, I imported the WorldWonders DB, was able to define the column for shape. I defined points for the polygon just around the outside of the colosseum. Saved the shape and the mission did not complete. I erased the polygon and redrew it with the points just inside the shape of the colosseum. No luck getting the mission to complete. Open to ideas about what to modify. Attached a screenshot of current polygon.
