Duplicating actor blueprint messes up component hierarchy

Hey guys,

I think this is a bug that’s been in UE4 in a while (only just tested in 4.18 and 4.19 though, with the same results)
If I duplicate an actor BP (via ALT+drag, copy paste, or CTRL+W) the hierarchy of the BP’s components is being reset (everything gets re-parented to the root)

Steps to repro:

  • create an actor BP and add 2 scene components to the root, save the BP.
  • drag the BP in the scene and add+parent static mesh components to each of the 2 scene nodes of the BP.
  • clone the actor in your scene and observe the static mesh components of the new copy will no longer be parented to the 2 scene components (they will be under the root instead)

See the attached image with an example
