RootComponent must be set for Simulate Physics to function properly
If an actor's Simulate Physics and ActorLocation/Rotation properties are set in code the editor will crash immediately upon launch / debug in VS.
1. Open UE4 Editor (any project)
2. Add code to project based on Actor
3. In the constructor add the following:
this->GetRootPrimitiveComponent()->SetSimulatePhysics(true);
4. In the Tick() function add the following:
this->SetActorLocationAndRotation(FVector(10, 0, 0), FRotator(0, 0, 0));
5. Compile
6. Open the project
