Well spotted, and welcome to the forums, phkb.
Now, this is an interesting one. The Constrictor is stolen from its shipyard, and the thieves can be tracked making two jumps before they jump out. The first is to a fairly low-tech world, but the second is to the TL 10 system (not sure why it looks TL 9 in your game - maybe an OXP changed it?) where they can buy a galactic drive.
Or where they would be able to buy one, were this Elite, where it was a TL 10 item. In Oolite, however, for historical reasons, the drive is a TL 11 item.
There's no particularly obvious alternative for the thieves, either. Xezaor is probably alerted to them and they can't afford to spare most of a day there getting the drive fitted to their very distinctive ship. Veale is the next closest but because of the topology of G2 would require a significant rewrite of their route through that chart. Inonri similarly. The rest are even further away.
Interesting...

The original mission notification can. The messages about the thieves' actions are specific to the system, though - the one where they jump out can only occur at this particular system.
