Maybe i didn't make this clear. The purpose of this is for the people in the city to "buy" a chunk of wood, if they duplicate it, they can have as much as they want, but with teh mover, they move it only, no duplicating it endlessly.
Sorry I didn't make that clear.
I think you're approaching this entirely the wrong way, then. Having people be forced to move a ghost brick around could be a pain in the arse, and simply... awkward.
Try using var events to add a variable to the player?
Otherwise, try using onProjectileHit --> Self --> Dissapear [-1]
