Considering they have aquired all scan data in that area and are now in incursion mode and filling the area might it be possible the probes are now to be found where they plan to go next? Wherever that is
NHSS 5-8... basically any in the range that spawn Interceptors-only. I found one in a Medusa (Threat 7) spawn, and one in a Cyclops (Threat 5 spawn). I only found a Sensor in a Threat 8, but since they're usually less common, it's more than likely if i was hitting Threat 8 regularly, I'd eventually find one.which level NHSS?
