When a scene is manually baked with PLM, after opening another scene light probes in the first scene go black.

1. Open Progressive scene.
2. Manually bake it. Notice that the sphere in the scene is lit with the probes.
3. Open Enlighten scene.
4. Bake it. Observer similar lighting.
5. Open Progressive scene again. All light probes are black.

If you open Enlighten scene again, everything there is fine. Happens only with Progressive Lightmapper when realtime GI is enabled

Workaround:
- Clearing the baked data, and re-generating lighting using Progressive Lightmapper without switching backends and scenes should address the issue
