Hi wicid,
I'm sorry to see you have gone such a long time without gaining new neighbours. As I have posted elsewhere on this forum, our development team are working extremely hard on this complex issue and will soon be ready to test some possible solutions over on our beta server. It was unfortunately not possible to test any solutions before the implementation of Tournaments. In the meantime I have again highlighted this issue in my feedback, and will continue to do so, as I know it is an issue that affects many of you, especially now Tournaments are here.
I hope you, and others in the same situation, will not need to wait too much longer before you get new neighbours.
