Calling RestartGame Function causes a crash when exiting PIE

If the Restart Game function is called in blueprints or code then the editor will crash when exiting PIE

[Link Removed]

1. Open UE4Editor (any project)
2. Add new blueprint based on actor (MyActorBP)
3. Add input event for R key press
4. Add "Get Game mode node"
5. From Get Game Mode node create RestartGame node
6. Wire R key press event into RestartGame
7. Set AutoReceiveInput to Player0
8. Add instance of blueprint to the level
9. PIE and press R
10. Press Esc to exit PIE

Result:
Editor will crash on exit

Expected:
Editor exits PIE after restarting the game
