I was only able to reproduce this with BP actors. In the attached image I also tried to do it with a Basic > Cone, but was not able to repro it.

In the instance of the warning above I used BP_AnimBP_Perf asset in QAGame.

I was unable to repro this on a binary build in //UE4/Release-4.15 @ CL 3403743

Steps to Reproduce


  1. Add an instance of a BP actor to the Viewport.
  2. Ctrl+z to undo placing the actor.
  3. Try to click on "BP Actor" in the Viewport.

After undoing the create actor, the actor is still in the Viewport. Clicking on the actor generates a warning of

LogEditorSelectUtils:Warning: SelectActor: The requested operation could not be completed because the actor has invalid flags. (BP_AnimBP_Perf26)

Undoing the create actor removes instance from Viewport.
