When loading a save (.mcx) from my phone into my Mac, the save appears to load, and I can see the region map. However when I click on a map in the region, I get an error saying that the save for that map can not be found. It seems it is looking for both region and city, but the save only includes the region. The same error is given for all cities in the region I loaded.
I've tried this several times with different saves etc. Same every time. Any ideas?
