Hi I'm on mac, whenever i save a new city and come back to play the next day its completely gone..

the file loads up fine.. but the city completely disappears but money remains..

anyone else run into this problem?

No, I will get back to you if I have high-grade amnesia and somehow buy an apple computer.
If Mac has a run as administrator and/or compatibility option, you should try that.

Having the same problem on Windows XP. Save loads but the terrain is just flat land. No rivers or hills. And no city of course.

I'm having the same problems, anyone found a solution?

I will be able to help you when I lose my mind and buy a mac.

BlaneckW. Why would you need a mac to help with windows issues?

he did not mention whether he run as administrator and/or compatibility

I'm having the same issue. Very frustrating, just built my Archipelagio (sp, whatever), and when I relaunched the game the next day. Flat map, everything gone. It happened in the year 2167...
Please help!
