This applies to city and countries where there are duplicate city names within the country.
In People, World Map (http://site.com/m/map_profiles/) the buildings are located on the map by city, country and can be incorrectly displayed when there are duplicate city names within the same country. A building could be displayed at Springfield, Illinois, USA and the site have no members in Illinois. The member could be in Springfield, Virginia, USA. The building location depends on which city is displaying first in Google (enter city, country in Google).
As per kolimarfey, "building are positioned using country/city pair - so I suppose that cities will still have problems..."
