Hello everyone, I never joined Simtropolis except that today happened exactly what happened to Joe90. I don't have a backup. This happened right after playing for a long time and clicked "Save and Exit to Region" the sand clock stayed there for a while, I went back and forth to the desktop to see if it would restar, then the city went crazy, it showed the city like when you see the region in "Transportation Mode" and it was switching to normal back and forth. After that, the city appears like a blue hole in the region. The file is there, same size. I tried loading the city in another block but that just created a new blue hole...
... any ideas? I didn't quite get Mr Giggles solution .....
Please HELP!! It was a 200k people city!
