1. Maybe you played in another browser(or some other sowftware).why isn't my save file working? it's fairly recent. it was on the 9th of June
2. Maybe you cleared cache from browser.
3. When Dev think that new version can not support that old version saves, you will not see them is save list.
4. When you clear all current game content or played enough, save your game AS FILE, and save it in game folder. this way you will not lose save.
