I think there might be a bug causing eco footprint to reset to neutral when you leave your lot. After nearly two full seasons of work I managed to get Port Promise up to a green eco footprint. It stayed that way for like 3 days, during which I also began the Green Initiatives in Port Promise NAP. At this point though both of my sim's in laws died within a day or two of each other, and I went to their lot to see if the urns could be recovered, and when I came back I was informed the footprint was neutral again and the bar dropped from full green to both sides empty in only a few in game hours. I spent several more days on hyper drive trying to get it up again not understanding why it dropped out of nowhere. I renovated my house, and also every other building to have as much green footprint as possible, and finally after essentially filling my yard with wind turbines and dew collectors the arrow finally turned green again and the bar started filling. The next day I went to the Romance Festival, and when I got back it was back to neutral and dropped to empty again. Has anyone else experienced this, and did you find a work around for it?
