If a scene is built as an AssetBundle and is Loaded in another scene, Global Illumination will work in Play mode, but not in Build.

Note: Global Illumination will work in Build if it is not Loaded.

Reproduction Steps:
1. Import attached project.
2. Open "GI Scene" scene.
3. In "Window" -> "Lighting" press "Build".
4. Press "Bug!" -> "Build Bundles" in menu.
5. Open "Loader" scene.
6. Enter Play mode.
7. Observe Global Illumination in Scene.
8. Build and Run the "Loader" Scene.
9. Observe lack of Global Illumination.

Expected result: Global Illumination in Build is identical to Play mode.
Actual result: Global Illumination doesn't work in Build.
