REGRESSION: No, this occurs as far back as 4.22.

Duplicating two nested components can result in the duplicates not being visible in the component tree in the blueprint editor until the user compiles.

This seems to only occur if the user selects both components and selects the parent component last.

Steps to Reproduce
  1. Open QAGame in editor.
  2. Create and open an actor blueprint.
  3. Add two scene components.
  4. Nest one of the added components under the other.
  5. Ctrl+Click the nested component and then its parent.
    • Important. If you select the parent first, the issue does not occur
  6. Ctrl+W.


The duplicate components are not available in the component tree. Compiling the blueprint makes them visible
