ACTOR LIGHTING NOT RENDERING

I have a scene that I am working on and suddenly, the actor’s lighting are not working when I render the shot in sequencer. It is a night scene with a spaceship. The spaceship is surrounded by lights, to of course, illuminate the spaceships. In my viewer the lights work. When I preview the scene, the lights work. However, when I render the scene in the sequencer, the lights are turning off or not working. Anybody have an idea what is going on here.? It was working fine for days and last night it wasn’t.
