Looked at the binary system the game generated with the system and figured "Hey, would be cool to have a nice little belt going on between the two stars", wasn't until about 40 years in and I was pushing out survey ships to survey the home system that I realised the sheer distance between the two stars and that I'd ended up with 880 asteroids spread across 290 billon Kilometres well well weeeeeeeeeeellllll beyond the scope of the standing orders detection range of new targets.... now been some 15-16 years mapping out these asteroids using 3 survey ships.
Sometimes I get lucky with a close cluster that allows a survey ship to chain survey 10 or more before they start whining there's no more asteroids in range to survey, but for the most part the limitation on standing order range has turned this into what will likely be a two decade long survey micromanagement headache. lol
But a good lesson to learn when doing another custom start.... always sanity check distances before tweaking.... that and to dream of a day when Steve blesses us with a option to tune standing order ranges within the standing orders window.
(Edit: Come to think of it, might be closer to 20+ years already spent mapping the asteroids out, I think my brain is trying to repress the memories of manually babysitting these survey ships for all this time)
