I am not sure if this is intended behavior or not, but it is inconsistant with moving orchards at least so it is confusing to a new player.
I had zero production left.
I attempted to move a guard tower.
Instead of moving the tower it credited me half the cost (as would be expected with recycling) and then attempted to charge me full cost to place the building again.
Thus I essentially lost the tower by trying to move it.
If this is intended behavior, it should be made clearer that some buildings, if you move them, it will cost you have the price of the building to place it again.
(edited to add) ok, so I guess this happens with buildings, but not food production plots. In which case my bug report is 'this really should be clearer'
