These are things which can help you: 

• Use save as and a new name instead of save
• Try saving in Edit Town mode as well as live mode
• Try saving your game paused and unpaused and at different speed levels.
• Move your saves folder to the desktop
• Never use save & quit. Always save your game first and then quit the game without saving.
• Don't use spaces or special chars in your save game names.
• If you have lots of stuff in your inventory, reduce it.
