Tracking transmitter. Im missing this investigation in the Outer Caverns. I wasted an Radar Enhancer trying to get to it. When I go to the spot there is nothing there yet the action button or the red circle appears above my head even though nothing is there. If I press it my character will go through the motion of looking around as if collecting an investigation but, nothing. There is no humm for its indication or a physical green node. You can only tell where it supposed to be by the Radar Enhancer and the action button indicater
