Since last week my neighbors have been reduced from 80 to 60 to 30 now down to under 20 neighbors. Is this normal?
If you're on a new world there tends to be a bunch of players starting who then become inactive and their cities disappear from your view. Hence the hood sizes shrink. It tends to be corrected in a few weeks when these smaller hoods are merged.
If not in a new world then ?? Much opf the organisation in this game remains a mystery!
