Night scene.

Hello! I have a night scene with the building, inside which there are sources of light. Initially, the scene was build with the included sources, but now I need to disable some and add the ability to enable their turn on.
I disable some light sources and start build. After ~15 hours the process ended and I see that the room is still illuminated, but weaker. What am I doing wrong? At the moment, i’m enable: “Overridden light map res” on all the objects and build again.

Oh Yes, in those rooms where there were no lights, everything looks as it should, they are just dark.
