Bugged, it is hard to miss normally as to where you deploy probes, as it shows you little glowing probes that you click on, in the area specified by the mission. It has been bugged since Dantooine came out. The probes you click on are not visible and for destroying probes, for the toons I tried it on they clicky icon never appeared. I have been doing this since it came out so I know exactly where they are meant to be.
