Bug with setting the ChildActorClass in ChildActorComponents in Blueprint

It's impossible to set it back to None. Also, if the original blueprint had something set in ChildActorClass, it will be impossible to set a placement of it to None. I looked at it briefly in the debugger, and it does initially set it to None. However, when the actor is destroyed and re-created, it reads the old value back in during serialization.

• Create a blueprint, and add a ChildActorComponent.
• Place that blueprint in a level
• Go to the ChildActorClass in the details pane, and set it to anything. Any Actor works.
• Now try to set the ChildActorClass back to None.
