Those should be fixed as well. In essence, we wanted to make sure you get the same fixes found elsewhere. If possible, please play through the affected parts and let us know if you are still experiencing the same exact issues.
I've just finished the Georgia Avenue map without any problems. I've created a support issue:
After GOG released the GOG Omerta fix, I've done a clean install with the new installer and started the game from scratch.
The recent GOG Omerta fix fixed the ending credits bug, the game breaking bug in Georgia Avenue, the bug in Garden Pier and 1 of the 3 DLC maps.
Connecticut Avenue and Industrial District are still empty, no people, cars and traffic.
The Suburbs map looks fine now, though I haven't played it yet.
