Eco Footprint desperately needs to be fixed or disabled for all world except the DLC one

People say the worlds gravitate to "Neutral" but in Briteshester for example the place definitely go smoggy. I mean true, Victorian style city with coal heating and fireplaces everywhere... of course. But anyway. The fireplaces in the student areas must be removed or the commons and Darkwing house alone will turn the place disgusting after awhile.
