I haven't had any problems with eco states in particular, so I wouldn't like then turned off. They do naturally move towards neutrality, as confirmed by the devs in all the prerelease information. When I do not mess with anything (actions or builds), all the worlds always stay or becomes neutral. I will admit I haven't turned it off, though. If something is bugged out there I would not have a clue.
However, building is supposed to have pretty a large impact on this over time. Specifically all the buildings in the neighborhood. I'd 100% check if you have a bunch of BB with a certain eco score if it seems slanted.
