Well, While I'm playing, all the achievements and upgrades are kept, no problem. It is just when I stop my session and login later on, all the achievements and upgrades are gone, and I have to start from nil on again. There is a save/clear button, but it only clears the achievments, no save is done. I would like to continue my achievements next time I log in. But I cannot find the way how to save the game even with an armorgame account.
As Unleashed said,there is a setting which clears save files and cookies when you close the browser,so change the setting the settings or if you can't find the setting,try using another browser.
