Some of you had a problem with corrupted saved games
Now every time you save the game, a backup file will be created of that save
What to do if you want to recover saved game?
Go to folder with files of the game, then:
saves\games\Earth\
and find corrupted saved, in this example it will be "1543943864877peaoeoej"
1543943864877peaoeoej - is a last save
1543943864877peaoeoej_BACKUP - is a backup
All you have to do is to remove file "1543943864877peaoeoej" and change the name of "1543943864877peaoeoej_BACKUP" to "1543943864877peaoeoej". Just remove "_BACKUP" and backup save should work in the game.
