During runtime, the red coin in Stand 1.7 on the Blueprints_Overview map of Content Examples should emit a large spark particle system 5 times.
While investigating, I tried disabling "Use Fixed Relative Bounding Box" on the "P_spark_burst_2" particle system, and this seemed to help the problem some, but not entirely.
Results: Sparks do not play on the coin
Expected Results Sparks burst out of the coin 5 times
