I have a problem with World Partition, if I destroy an actor from the level, it respawn each time the grid is reloaded. What is for you the best solution to permanently destroy an actor (loaded with WP) at runtime?
Either the actor can be a blueprint, or there can be a blueprint which manages actors.
When the actor is destroyed, this information gets saved to the save game.
When the actor reloads, it checks the save game. If it has already been destroyed, it then destroys itself.
