I have a copy of black and white each, and via entralink I talked to the black city residents with white version and talked to the white forest residents with black version. Through this I got 3 residents to move from black to white, and 3 to move from white to black. After that I can't seem to grow my black city and white forest any further. Subsequent entering into entralink of each side, the remaining residents do not give me the option to bring them from white to black or from black to white. Any solutions?
Do i have to enter different white-forests/black-cities each time? i.e. different white-forests/black-cities belonging to different profiles?
