I'd like to argue that. I do not know if it is because of the new immigration system, but Rettleville receives 20-35 peasants per day, while Rettlewood, when still under our control had counts above the 100 per day.
Cities on Dwilight can suffer badly under the new immigration code. Apart from births, they rely on the surrounding townsland to provide immigrants. If that townsland is under populated I would assume immigration can be rather slow. For Rettlwville to grow at its maximum potential you will need to hold Rettlewood and some other surrounding regions in order to secure a steady immigrant supply. If you can grab some regions that border fully populated regions, then they should grow even faster and that should trickle through your realm as well.
