    I've got a similar issue in Unity 2018.3.8f1. Most of my spot-lights are vanishing when I start baking my scene. The lights are still there, but they aren't lighting anything. I had to duplicate all the spot-lights to stop to get the lighting to show up. The other way I can get the lighting to show up is by deleting the backed light-map folder and all its content. By the way, this is the second ticket where I've seen this exact same problem marked as fixed, and I've been having it since Unity 2018.3.2f.
