There's a crash when "Play Quantized" is used on an Audio Component that was constructed via the functions "Create Sound 2D" or "Spawn Sound 2D" when the option 'Persist Across Level Transitions' is checked, due to GetWorld() returning null within the Play Quantized function.
Expected Result:
Actual Result:
