Child actors bug in World outliner

I think I found a error in World Outliner.

Steps:

  • Create an actor with child actors inside this.
  • Put this actor in your scene.
  • Create folder “Example folder” in World outliner and move the actor inside this folder.
  • Edit this actor and add a new child actor.

Error: the new child actor is shown in root World outliner instead of inside the root actor in “Example folder”.

Ok, it was not a bug. The actor was Static but the child actor was Movable. If I put the child actor as Static already looks well inside the folder.
