Universe Restart?

Don't forget to allow for other data that they themselves scanned, outside of their domain, or have sensors enough to cover via airport radar.

Could do super sector on their domains maybe, that way they would have sensor range around their cities to some extent.

But having all systems that have surveyed would be too much work, as the servers would have to keep travel of who has scanned what systems for what empire. Not worth it for the effort.
If they want to be able to see the surveys of systems that have surveyed, they should just either go there, or make a city to have domain in the area.

That is assume any of it is even possible for Haxus without butchering the whole starmap.
