Update to version 1.59.2.133348 this patch puts cities back to normal
In MY case it was because services no longer cross bridges. Remove the bridges and replace the water underneath with roads.
This was the case in my Capitol city. I don't know if it's the same in regionals as I don't have any isolated communities which aren't connected by Game Bridges.
Hope this helps. Hope even more it's a bug which will be fixed as now my Estuary and Mountain outlets are orphans
same for me
i did the last update and it made all my omegas building having probleme ( not covered by control net , drones.... sewage....) in both capital & region
did nothing else than updating game ...
been playing since beginning, lost 5M pop in my capital
please EA , fix this bug , not the best way to celebrate 10yrs anniversary
