Hi, I have a farm lvl 16 and I'd like to go to different state.. I know that I can't, but if I open a new game and find my old farm in different state what is the best way to do? I can't just open my gate to another player? Or there is not a place where are trading profiles? Or? ... nothing then take off my own farm? Thank you
