It seems that the City Sample project is broken under Unreal Engine 5.7.
Traffic and Crowd are not working, I get errors like:
LogMassSpawner: Error: No locations found on zone graphs
The map “MassCrowd” under the AI folder, works without issues.
Is this a known problem with 5.7? I downloaded the project from scratch as it was tagged to be compatible with 5.7, but I have no traffic and no crowd.
