A static object using 'Complex as simple' collision will not collide with a dynamic object that is simulating physics

If a static object has 'Use Complex collision as simple' set as its collision type, it'll collide with a player but will not collide with objects that are dynamically simulating physics.

1. Create a new project with starter content using the First Person Shooter template
2. Create a new blueprint based off the actor class
3. Add a static mesh component to the new blueprint
4. Apply a static mesh that uses 'Use Complex collision as simple' (i.e. Floor_400x400)
5. Place an instance of the blueprint in the level and be sure that 'Collision Preset' is set to 'BlockAll'
6. Place one of the FirstPersonCubes in the level over the new blueprint's instance.
7. Start PIE
8. Notice that the cube falls through the new blueprint instance
