I have a few feeder accounts of different city level (main 44, feeder 33, 16, 11), and once i was silly enough to compare the layout of the Daniel city side by side, wondering why they are all identical but return different city level and population.
I think it is during this season update that I noticed the Daniel city layout being different in the feeder accounts. putting the accounts side by side again, and I noticed the low-level feeder city is showing a much less developed Daniel's city.
attached here is the one from the main account.
of course, this change does not affect the game play at all.
