Callback after loading editor for items on a saved map?

I have my map saved with some settings on the components set up. In particular, a link of an actor on the scene.

When the editor opens, this particular component gets created and deleted several times, just like other game engines.

On the constructor I try to gather the pointer to that actor through the component to make sure it’s not NULL, but the editor is never created and this UPROPERTY is not set even after all those constructor executions of the component, so it’s always NULL unless I call the function after everything is loaded, by hand.

Is there, like there’s in Unity, a function which is called for every actor and component right after everything is loaded in the editor so that you can establish links between actors, components, etc?
