Black areas on terrain keep appearing

[cpullma]

There are some areas on the terrain that are darker, but aren't visible from certain angles as I rotate the camera around. I delete the Library folder, open the scene back up, and it's gone. Then I close Unity and bring it back up and the issue is back.

As per discord. 
This is a Unity Shadow issue.

The only way to fix it was to use the procedural sky option instead of the "Day" option.
