That's amazing. They're so far out of the gravity well that when I tachyon'd and sniper'd the three EtherJets, it STILL took three and half minutes for those fighters to make it back, moving at speed 672.
I think the original cause is the Player 2 Radar Jammer Mk II on the planet. The EtherJet's range is reduced from 5000 to 2500, but the tractors hold the targets at distance 4500. So the EtherJets continually move towards their target, which is held by the tractor beam at a fixed distance, so it continually moves away.
I know there is a special rule where tractored units can always shoot their captors, regardless of range. I'd thought there was a similar rule for tractoring units and their targets, but I guess not.
Sounds like something that needs to be fixed.
Even if it is amusing.
