StaticMeshComponent occasionally doesn't simulate physics after SpawActor.

When spawning Pawns with a StaticMeshComponent with SimulatePhyscis=True, they occasionally may not simulate physics. This can be reproduced by simply repeating the respawn. The frequency of reproduction is about once every 2 to 10 times.

If it doesn't simulate, it can be reproduced by re-setting SetSimulatePhysics(True) on the StaticMesh.

1. Open the attached project.
2. Play in editor with NewMap level.
3. 50 Pawns with StaticMeshComponent with bSimulatePhysics=true will be created. Press [1]Key to respawn.

1. Repeat until can see a StaticMesh that doesn't simulate.
