Server Streaming breaks Mass Replication / LoD

Steps to Reproduce

  • Setup a WP level with Mass, configured to show low-fidelity static meshes at a distance and real actors nearby.
  • Use very different static meshes so the transition stands out.
  • Confirm that the entities get promoted to actors and demotes as you move around.
  • Once you turn on ServerStreaming the low-fidelity representation disappears
