Unity breaks top asset material and looks like a missing texture

1. What happened
After importing ˜Attack Zombie Mobile ZPS˜ asset in 5.6.0b3, the scene looks like missing a texture.
If you open the material located in MobileTPS/Material/Scene/Scene.mat, it looks differently than if we open the project in a previous working version (5.5.0f3)

2. How we can reproduce it using the example you attached
Just download ˜Attack Zombie Mobile ZPS˜ package and compare it with how it runs on a working version (for instance, 5.5.0f3)

Non-reproducible on Windows!
