There should be a feature so whenever you attempt to close the window or soft restart it asks if you want to save. I have a macro right next to my escape button and after only 3 days of game play, I've pressed this button many times and have lost many hours of game play. I know it's my fault for not regularly saving but it's just not a habit for me since most games these days either have a prompt when quitting or an auto-save feature. Thanks!
