When a component delegate is called in a blueprint as an event, changing levels causes the delegate to loose binding and not be called.

Steps to Reproduce

This has not been reproduced internally (Steps based on report)

  1. Open UE4 Editor
  2. Add code to project based on Actor Component (MyActorComp)
  3. Add the following to MyActorComp.h
    • Add below list of includes:
    • Add inside class declaration:
      	UPROPERTY(BlueprintAssignable, Category = "test")
      		FCompDelegate CompDelegateTest;
  4. Add the following to MyActorComp.cpp
  5. Compile
  6. Add blueprint based on actor
  7. Add instance of MyActorComp to blueprint
  8. With MyActorComp selected in component hierarchy, click the plus button for Comp Delegate Test to add event node for the delegate
  9. Wire print string node to event node
  10. Set Class Defaults > Auto Receive Input to Player 0
  11. Add input key event and connect Input event > Get Current Level Name > Open Level
  12. Connect Get Current Level Name - Return Value to Open Level - Level Name
  13. Place instance of blueprint in the level and PIE
  14. Press input key

Print string attached to the delegate event will print when PIE starts but does not print after restarting the level

Delegate triggers each time the level is loaded.
