After calling Seamless Travel, actors in the level will not be in their original positions. The example provided by the licensee had a different result: the actors, despite having Start Awake disabled, would respond to gravity.

Reproduced in 4.10.1 binary. Licensee included a project in the UDN post, we reproduced a slightly different result in a new project.

Steps to Reproduce

1. Open a new blank C++ project
2. Create a new C++ GameMode class, "BaseGameMode"
3. Add this code to the .h:

class ACTORSELECTIONTEST_API ABaseGameMode : public AGameMode


	UFUNCTION(BlueprintCallable, Category = "Default")
	void SeamlessTravel(FName LevelName);

4. Add this code to the .cpp:

void ABaseGameMode::SeamlessTravel(FName LevelName)
	FString Cmd = LevelName.ToString();

	GetWorld()->SeamlessTravel(Cmd, true);

5. Compile
6. In the editor, save the map as "StartMap"
7. In the editor, create a Blueprint based on BaseGameMode
8. In the BaseGameMode BP, enable Use Seamless Travel
9. Event Begin Play > Delay (2 sec) > Seamless Travel (LevelName = "StartMap")
10. Create an Actor Blueprint in the editor
11. Add a static mesh component
12. On the static mesh component, set Start Awake to False
13. Drag 3 instances of the BP into the level
14. PIE

After travel, the 3 BP instances are teleported to the same location. In the licensee's example, they started awake instead. Neither result is expected.
