My save is gone, can I restore it?

The only way that your local save file will be lost is through Steam cloud synchronisation issues. 

If you do switch computers and rely on Steam cloud then please backup your save just to be safe.

To mitigate this issue, there is a local backup save directory located at :

To get to this folder use Start > Run and %localappdata%/playne/saved/SaveGames/Backup

This should have your most current unsynced save file. Please have in mind that, if you play the game after this, it will overwrite your backup folder. 

How do I use the backup save?

Simply move the files from /Backup to the /SaveGame folder
