Bug Running Simulation Actor BP

If you start the simulation in the Blueprint editor and BP spawns Actors they do not disappear after you shut down the simulation. This can build up to making the editor run at a very slow frame rate and balloon memory usage.

Only way to fix it is to close the BP and open it again which clears all the spawned actors.

If you disable the spawned Actor you will still have the old Actors sitting in the window and they do run simulation when the sim button is triggered again.

I am looking for a better way to prevent this from happening than closing the BP down and opening it again, an editor option that clears simulation created spawned actors.

Still a pain anybody have a solution?
