HDI get objects to not reappear when I return to layout?

I have collectables in my game and the player can leave and return from some levels. The only problem is when I am returning to a layout all the items return to their place after being destroyed. For enemies that is fine but I hope someone can help me out. Maybe it has something do do with the behavior that allows you to save?

Hiya you are looking for the 'Persist' behaviour. Add this to the collectable object and they remain destroyed when you return to the layout.
