I stupidly placed my first hub link between Circle of Labour and Omicron Lyrae. A bit after that I accepted a patrol mission in Nyanas Hideout that ends in Circle of Labour - in other words, it goes through the hub sector.
All went fine until I jumped in there. A few Kha'ak ships spawned, but only one of them inside the actual construction. A Corvette and a Carrier are -4294967 meters (yes, negative number) away from me according to the targeting system. That number does not change even if I move my own ship. (Let's see.. 10m/s going backwards?

There is also a Corvette 4289km away from the centre.
They sent a few missiles after me and the beeping noise was constant, that was pretty annoying

I can provide a save game and any other info if it's needed/wanted.
(as for scripts.. I run CAG, EST, CLS 1/2 and Prospector.. I can't imagine any of them messing this up .. but seeing how I do not know how things actually work, I'm not going to claim I'm 100% on that)
