Realtime GI stops working after I click "Generating Lighting"

Unity Engine

Here’s a short video that shows the behavior I’m seeing:

In my test scene, I have a sphere in the air that has an emissive material on it. I’m changing the emissive color with DynamicGI.SetEmissive. It’s set to Static. There’s a cube to the left that’s also Static, and another sphere on the floor that’s not Static. The room is set to Static.

The specific issue is that if I tweak a lighting setting (in this case, Albedo Boost) and click Generate Lighting, then Play, things looks good. The emissive color is bouncing off the objects in the scene:

However, after playing, if I simply click Generating Lighting again, then play again, the results are totally different. The emissive color only affects one of the objects in the scene:

Has anyone else seen behavior like this? Between the two screenshots I’m done nothing but click Generate Lighting.

Looking into this more, I found this doesn’t happen if I turn off Mixed Lighting. More specifically, this doesn’t occur if I use Enlighten, only when I use Progressive.

I thought realtime GI was Enlighten-only, or is it supposed to work with Progressive too?
