You need a pretty high system population to start needing to break Open supercruise into two or more instances in the first place, though. CGs may be the only common case of that.Interesting. I'd be curious to know if the system security level affects how strong of an influence wanted status has on instancing (if it does in fact have an effect at all). Making high security systems aggressively separate clean from wanted, low security systems moderately separate them, and anarchy instance them together freely sounds like a very effective way to make security level meaningful.
I'm still inclined to think "unintended consequence of prefer-instancing-with-friends", and perhaps they increased the weight of that further in 2.3.10 or 11? I've certainly been instanced in the last few weeks with people of different legal status - but that's been in relatively quiet systems which probably only had one Open supercruise instance.
The obvious test I guess would be "does it still happen in Anarchy CGs?"
