Ever lost a city with corrupt save and you not backuped it? Don´t worry, I found another way. It worked to my. I´m not sure if it will work for everyone-2 older saves can be also corrupt. Backup for sure. Follow the instructions:
1.Allow displaying known file extensions
2.Go to C:\Users\YourName\AppData\Local\Focus Home Interactive\Cities XL 2012\live\offline\solo\solosaveregionXmapXX\auto
If it will not work with old try with old2
4.You are done!
Note: May not work, works only if previous saves weren´t corrupt
