That's fair and I can of course double check myself as the last time I used hive was some time ago and it seemed to be going both directions for me personally, though I do play modded a bit more chaotically than I think most people would prefer or at least from what I've seen. Either way though I can go ahead and start checking once again to make sure I'm not going crazy or should be simply shut up.
As to adjusting their accessibility, I am not sure I could do that without severely effecting their growth and income generation, both of which are core to their invasion and colony fleets.
Yeah ok that makes sense. I was more just speaking from the terms of the immediate early game where when one would start looking for things to generate income and suddenly instead of being able to find any good markets to buy from they get to see the hivers having their commodity markets over produce like mad and being the "best locations to buy from" as clearly flying into hiver space is a safe and healthy option for an independent trader.
Counter consideration that I just had would be to try and balance out their productions to being net neutral and then giving their markets an accessibility boon so they neither over produce or under produce and of course once they start expanding out into new systems to colonize it starts to turn into a them problem producing the goods they need, that way at least the player isn't struggling to read the supply and demand menu right out the gates and having no real good idea as to where to buy anything.
