Unity 5 Terrain Shadows

I have been working on porting my game to Unity 5 and am constantly encountering issues. The first issue was the fact that baked/mixed lighting simply does not work correctly. After a recommendation, I was told tat the best way to go was 100% realtime with a large shadow distance (as in Unity 5 you can now adjust the cascade points).

Now I'm getting issues with these shadows appearing correctly when running the game. I have uploaded two videos, one in the editor. (Correct shadows)

And another when playing the build...

You can see the shadows do not rest on / respect the terrain.

Any thoughts? This is killing me slowly.

Saw this yesterday and can't really help, but since no one else replied so far:
Did you try to replace your vehicle with a standard cam? Maybe something on the camera or the windows shader mess with the depth. Just a complete shot in the dark, might as well be a bug.
