Steps to reproduce:
1. Click the Settlement Details button.
2. Choose Rename City
3. Change the name of the city and click Accept.
4. Close the Settlement Details window.
5. Zoom out on the map until the city's name is displayed.
Result: the displayed name is the old one before the rename.
Expected result: the new name should be displayed on the map.
