Couple things I've noticed so far - smaller one being that freelance equipment isn't being removed from the inventory after leaving, and the bigger issue I'm having is that whichever faction I'm in won't declare war or make peace as long as I'm a part of it, even if I'm just freelancing. They stay at perpetual war (as long as the enemy faction exists) or peace until I leave the faction, then declare war / make peace within a week or two of me leaving.
Edit: Also some factions are having a problem with gathering armies and starting offensives. They'll gather armies over a few days and then just suddenly change their minds and disperse. They'll do this constantly.
