Hi
@SmillaJaspersen So the whole "Centre of the World Map" does get batted about a lot by the Team and the Players doesn't it
So okay, laymans terms!
The desired effect of the recent and ongoing moves will (eventually) bring all Active Players towards each other, thus creating a far more active neighbourhood for Trade and Neighbourly Help. All inactive cities, will be moved to the outskirts. The moves however are dependant on finding an active space that meets your criteria. The space needs to be "Like for Like" containing the same Boosted Goods, and the same amount of Scouted Provinces. With that criteria in mind (and the amount of Players on each server), this is the reason why it is still taking some time.
The reason the option to remain was revoked, was to ensure that there would be no Players left in inactive coin mine cities. It was imbalances such as these, that prompted the forced move in it's first instance.
As active players are moved towards each other (and continue to be) the need to move will be lessened, however this will still happen from time to time if the system recognises a more viable, active position.
I hope this has answered you question
Kind Regards
Herodite.
