So it seems some of the live bounties just jump away whenever you get close. So I updated my Eclispe with all Grade A stealth gear and took it for a test drive bounty hunting.
Although the torpedos have 10,000m locking range, they only track for 8000m as demonstrated here. As is typical with the Skyline star map, it fails to work and I manually navigate back to Everus Harbor.
