[LightProbes] Probes lose their lighting data after entering Play mode when Baked and Realtime GI are enabled
Steps to reproduce:
1. Download the attached project and open SimpleOutdoorsA scene
2. Make sure that both baked and realtime GI are enabled in the Lighting settings
3. Make sure that Auto Generate is disabled in Lighting settings
4. Generate lighting
5. Enter play mode
6. Notice that light probes have lost their lighting data

seems to be happening even on the very latest version as of today - Unity 2021.2.0b12.
Everything seems to be working after bake, then one of several things I do can cause the light data to disappear:
- Move the object (doesn't always happen)
- Save scene (doesn't always happen)
- Enter play mode (always happens) -

I think it's worth mentioning that the bug affects realtime lights only, mixed ones don't lose their data in the probes.
Also realtime lights don't lose their data if only realtime GI is enabled.It is still problematic though as in some cases where you have more than 3 mixed lights overlapping, the 4th nearby one needs to be realtime otherwise it looses its light if you bake in Shadowdistance mode (which has a 3 mixed lights overlap limit).

Only happens when baking with plm. Every version I tried since plm introduction.

It's still there in Unity 2019.1.14. and not even a comment here. Unbelivable. I am really close to switch to other engine after 4 years of using Unity...

Addition: this data loss is observable only when baking light with Progressive Lightmapper. The problem was caused by the Ambient Light in Realtime mode.

Same. 2018.3.12f1. To be more accurate, only the indirect lighting data is lost in my case.
