Issue about PCG

Development Programming & Scripting Blueprint

I think I found a bug about PCG on 5.3.2, not sure if it has been fixed.
I attached the testing project with my actor and level.

The problem is mesh duplication. In the level, I had 2 actors, NewBlueprint and NewBlueprint2, both contain PCG components to generate static meshes, but as you can see, there are 3 mesh blocks in the level, while there should only be 2.

To reproduce the issue:

  1. Make sure PCG plugin is enabled.
  2. Open the project and drag in NewBlueprint, see the mesh generate in the level.
  3. Delete NewBlueprint in the level.
  4. Ctrl-Z to bring back NewBlueprint, see that no mesh is generated.
  5. Adjust the spline a little bit to see the meshes again.
  6. Ctrl-D to duplicate NewBlueprint to see the issue.
