Spawn Emitter at Location does not Simulate in BluePrint

When using the Spawn Emitter at Location node in BP the emitter will not spawn while simulating in BP. Other Spawn at location nodes behave the same way. The Cube actor was included as a test to eliminate some suspicions.

NOTE
Cube actor was included in test to disprove suspicions mentioned in comments.

1. Open attached project
2. Open ParticleSpawner_BP and go to viewport tab
3. Simulate in BP

RESULT
Cube spawns in BP editor

EXPECTED
Particle Emitter and Cube Spawns in BP editor
