If an actor blueprint is re-parented to another actor blueprint, it will lose information in the blueprint even if nothing has been added to the second blueprint that would change the child blueprint.

Steps to Reproduce

1. Open Editor (any project)
2. Create a blueprint (actor), name it "Test_Child"
3. In Test_Child, create a sphere
4. Compile, save
5. Create a new blueprint (actor), name it "Test_Parent"
6. In Class Settings, set parent to "Test_Parent"
7. Compile blueprint


Sphere disappears after compiling blueprint


Parent changes to Test_Parent, sphere does not disappear because Test_Parent is an empty actor blueprint and retains all of the same functionality as any standard actor blueprint.
