Complex Landscape Collision is always used

For landscapes, both the simple and complex collision are used when simulated against. 

Open the advanced vehicle template project.

Set the landscapes Simple Collision Mip Level to 5 (Verify that Player Collision and Visibility Collision views are different.)

Add a sphere to the level above the landscape with simulation enabled

Simulate/Play

Result: The sphere will collide with both the simple and complex collision.

Expected: The sphere would collide with just the simple collision.
