As per rulings:
A device cannot be placed so that a portion of the device would be outsidet he play area. If this would happen, play is reversed to before the device was placed—the device is not placed, any charges spent and other costs paid are recovered, and the player can choose to not place that device.
what happen for devices that has charges that cannot be recovered (such as mines, commandos, buzz droids etc)?
The game is revised to before as the action has never been done and the charge is recovered?
