Printing the result of the 'Get Move Ignore Actors' node will crash the editor.
The Licensee found the issue while exploring a workaround for this JIRA:
https://jira.ol.epicgames.net/browse/UE-14734
1. Open QA-Game
2. In the Content Browser, find & open bp 'Projectile'
4. In the Event Graph, create the bp from screenshot #01
5. Select the Projectile (self) component
6. In the Details panel > Input > Set 'Auto Receive Input' to 0
7. Compile the bp
8. Back in the editor > PIE
9. Shoot the projectile with the Left Mouse button
10. Before the projectile despawns, press 'E'
Results: The editor will crash
Expected: For the Print String to print the actors that are being ignored
