Incorrect shadows displayed after importing the "Ultimate FPS" project. The editor needs to be closed and the project reopened.

1. What happened

Imported the "Ultimate FPS" Project into Unity 5.4.0b17. Launched a demo scene and noticed incorrect shadows displayed (dependent on camera movement, see the attached video).
Exiting and restarting the editor seems to fix the issue.

2. How we can reproduce it using the example you attached

- Download the Ultimate FPS project from the Asset Store;
- Open the UFPS/Base/Content/Levels/SkyCity/UFPS_SkyCity Scene;
- Rebuild the lighting;
- Enter play mode and move the character and mouse around. Notice weird shadows appearing (see the video). This is also visible in the Editor when panning/moving the view around.
