Lighting disappears when switching scenes

Hello -

I am building a game where I have an video scene that runs all the cutscenes and intro videos, and a main scene for the game. After a video is completed, the scene switches back to the main scene. Normally, the main scene has a directional light with black light (which seems a bit odd but it matches the "no light but still visible" theme I'm going for). However, if I start the game (in the editor) from the video scene so I can run an intro video, when the game moves back to the main scene the black lighting does not shine and no lighting appears. NOTE HOWEVER, if I create a build and perform the prior actions, the lighting does show up as normal. Also, my ambient light is set to skybox for both scenes and the lighting is realtime. Is this a bug in the editor, or some glitch that keeps occuring? Thanks in advance!
