How to definitively destroy an actor on runtime

Hi all, I’m having severe problems about performance on my project. I saw that the number of actors in the game raises from the 50-70 average at the beginning to like 2000 after 10 minutes of game with a (predictable) performance drop.

I have ofc the “actor destroyer” service in my blueprints that kills every no-more-useful actor in game, but the destroyed actors didn’t full get away, they remain as “deleted actors” in the scene outliner.

How do I fully delete them?
Thank you.

Hey,

just asked google for this. Seems like Epic tries to fix this in 4.7

So it’s just an error of the UE4 and doen’t depend on my work?
