Can't save level, Uobject reference on actor class

I’ve been trying to solve this issue. It appears to be similar to this post

I have an actor class that has a Uobject referenced. When I place this actor class into the scene in the editor, everything works fine. I can see what is supposed to occur. However, when I try to save the level, I get the error

"Can’t save …/…/…/…/…/Unreal Projects/BallsOut 4.8/Content/Levels/BallsOut_01.umap: Graph is linked to private object(s) in an external package.
External Object(s):
Maze_2
/Engine/Transient

Try to find the chain of references to that object (may take some time)?"

The Uobject is setup in the Actor class like so:

UPROPERTY(EditAnywhere, BlueprintReadOnly, Category = "mazeData")
	UMaze* theMaze = NewObject<UMaze>();

When I manually place the actor in the scene I can see “theMaze” in its properties box.

I never found a solution to this. I see many people run into this. Could someone provide an example of how to have an actor class with a custom UObject newobject<>? Also how does the intializer for this custom UObject class look?

This was crazy simple and I made it more complicated than it should have been.

In my actor classes header.

someUObjectType* nameOfSaidUObjectType;

in the .cpp of the actor class that is going to own this.

nameOfSaidUObjectType = CreateDefaultSubobject(TEXT(“SomeIdentifier”));
