I stumbled on this enligthening reddit thread today

Apparently, the player colonized systems influence significantly the factions missions available in nearby systems, enough to wipe all-time favorite mission loops out of existence.

TLDR; say good bye to Robigo passenger missions, Imperial ranking loop Ngalinn-Mainani , Federation ranking loops Ochosi / Chakpa (courier) Ceos->Sothis (passengers), Qi yomisii massacre missions stacking, etc... as soon as a colonization bridge reaches them.

To go off the other answer, specifically, there are - or were, I guess - several systems that were isolated, with only one or two neighboring systems within range to generate a mission to, resulting in an isolated little pocket of tightly-knit systems that have missions to each other. You could set up a nice little back-and-forth or triangle route, and the missions all paid well, so you got good progress. With the new update, all those systems are getting drowned in player-settled systems, so the triangle gets exploded.

Colonization has killed my home system. Went from 5 factions giving missions to a single system to the factions splitting their missions between 4 new systems. Big sad. I nearly guarantee robigo will be gone soon too.
Basically it's going to be a bit harder to grind out money, your faction ranks, etc. It will probably devalue the ability to make money by doing combat, at least at the upper levels. Who knows if there will be some other changes, but there's always been well known locations to get certain things. Robigo passenger missions are great for a newer player to get money, mats, and rank, but those will change as people colonize more nearby systems as it changes how mission generation works due to the bgs

Except I have a chain of systems already halfway to Robigo. When I get done setting up a tourist system nearby nobody will be doing Robigo missions anymore

Just checked: Ngalinn-Mainani loop is already compromised
