Project crashes without callstack when rotating an actor that has been made up of other actors

User Creates an actor with a static mesh and then adds more components to it. The user then separates these components from the actor transforms them and then adds them back to the original actor. Upon rotating this actor the project will crash.

Note: adding a Scene component as the root of "CrashTestActor" allows for the actor to be rotated without crashing

1. Download attached project
2. Play In Stand alone
3. Notice the Project crashes after the mesh makes a 'T' shape (just before the call to rotate the actor)

Crash on Set Actor Rotation - 4.9 only
