Baking lighting manually (not using the continuous baking) with reflection probes will result in black objects.

To reproduce:
1. Import the attached package
2. Open scene "GI_Fail". It has a few static objects and a reflection probe (realtime)
3. Open lighting settings
4. Press bake
5. Enter play mode - notice that the scene objects are now black

Using continuous baking fixes the issue. Using a baked reflection probe also fixes the issue.

This is most likely by design, but a warning about using realtime reflection probes with non-continuous baking would be helpful
