You know that bug that you get with large projects / randomly generated stuff? It's a glitch where inside of the editor you can see all of your stuff that was in game and some things are even MOVING in the editor?

To solve this it's so simple =D Just put a key down event on everything that has the glitch effect, make it "esc" and do "Delete Actor - Event Actor" Problem solved, now when you press ESC to return to the editor it wont bug! =D

I also got this at my jet game. As I exited from the Game Mode one of the enemy jet flew downwards in the editor.
I think someone said that is a memory bug.

When I do this, I add the escape key to the view, and destroy all actors from there. That way you don't need many many events for just destroying things.

Ahh good point sky
