  2. Open the project and look at the two Niagara systems in the level verify that one has particles in a ring, and the other appears to have no particles
  3. Open the output log and verify the NaNs have been logged
  4. Open the system that has no particles in the Niagara editor

RESULT

The system will work correctly after opening it in the Niagara editor
