That merge theory is completely false, I'm on my third week and only now I've been moved to another neighbourhood.
Problem is if my previous one wasn't that great for trading this one is just impossible, and from those two scenarios i much prefer my old neighbourhood, which I actually got used to even tho it only consisted of 13 players.
I would consider the ideal situation a neighbourhood of 36 with me already included, 5 way ahead in research 10 about the same level and the rest more or less the same and below.
I contacted support a couple of hours ago, and got no reply, and I know of cases who got transfered to their desired neighbourhood to this kind of ideal I just described, so I would much appreciate i would get transfered to the desired format aswell, thank you.
