SpecificCityInfoDirty

Fired when something in a particular city was changed.

Example (from SmoothCityBanner v.2 mod):

 function OnSpecificCityInfoDirty(iPlayerID, iCityID, eUpdateType)
     if (eUpdateType == CityUpdateTypes.CITY_UPDATE_TYPE_BANNER) then
         local playerTable = Instances[ iPlayerID ];
         if playerTable == nil then
             return;
         end
         local instance = playerTable[ iCityID ];
         if instance == nil then
             return;
         end
     RefreshCityBanner(instance);
     end
 end
 Events.SpecificCityInfoDirty.Add(OnSpecificCityInfoDirty);
