I've been using this mod for a while with my heavily modded Nex stuff, since I throw in so many factions the vanilla Sector is pretty crowded, surprisingly. However, something I've been curious to as I play more and more with this Grand Sector mod...
Does it seem to mess with the system generation somewhat? I've always heard that, in general, to encourage the exploration and use of further away systems, the game tends to generate more valuable/higher class planets and salvage in the further away systems. But I don't think I've seen this reflected when using this mod so far, I don't think I've even seen a Cyrosleeper still, and I do find a lot of pretty trashy systems even in the far reaches of the sector (or some without any planets at all).
This might just be confirmation bias, of course, or that system generation/spawning doesn't actually work that way.
