For some reason I am not able to recruit new immigrants in Europa, nor does the emmigration work.
I tried to recruit an immigrant the round before the number of crosses would have caused an emmigrant to appear, but when I tried to purchase one, the server disconnected and asked for a reconnection. Upon reconnection, no immigrant was on the docks.
Similarly, when I end the turn, the dialog will show, asking which emmigrant I want to choose, but a disconnect will happen again.
See the attached savegame.
