Steps to reproduce:

1. Open project "MixedLightGIBug.zip"
2. Open scene "Scene_9_Light_test"
3. Open Lighting tab and build lights
4. Build and run scene and notice that cube displayed in build is darker compared to editor.

Also, errors are printed after build is complete:
GI output for inputsystem: aad29279acef2d879e7ba687f143d86e (aad29279acef2d879e7ba687f143d86e) is missing.
