It probably did, have you played any save games?

it happened to me with some games then i refresh and its fixed

Really?? Not for me D:
A majority of the games that save broke for me :/

It could possibly be your IP address. Some ISP (internet service providers) have a system that assigns you a random new IP address every time you log on the internet. This could possibly be your problem.

It's happening recently with all the games I play on AG. Most recently The Last Stand: Union City. Pretty frustrating. I'm on IE. Cookies enabled, should be saving but it's not.

If it's a Chrome issue, that would be irritating because I can't stand IE and Firefox slows everything down so much I might as well not play.

I use Safari as my browser, I haven't had any problems with it maybe try it. Be warned though if you don't go to a website in like 1 month it deletes it from your history.

Now I'm on Safari, I haven't had this problem (if I did I can't remember). But every save file is fine and just where I left off. So try Safari it works great and is fast and quick (unless the page is super super big).

This seems like a severe technical or even physical problem with the computer. What operating system are you using? This information can be very important unless it is a boot level problem.

There are many levels it can come to:

(none)- There are no problems '1'

(simple issue)- Cookies or temporary files are set to delete '2'

(browser issue)- The internet browser locks up or does not save files in a game, It may also be the game itself. '3'

(OS issue)- The OS you are using bugs up when trying to save files on all browsers. Use system restore or recovery to fix it. '4'

(Boot issue)- No matter what OS you use, you cannot save files on any browser. '5'

(Severe boot issue)- No matter what OS you use, you cannot save anything even if it isn't on your browser. '6'

(Physical partition issue)- You take the hardrive to a completely different computer, only to have the same issues. '7'

(Total issue)- The entire computer in itself does not boot correctly and deletes the save of your OS. This is a total problem and you may not be able to login to AG at all. '8'

It happened to me on Mega Miner. I got so far but its to long to restart.

Okay, I'm having the same problem too. It happened to me in Firefox and Chrome. I didn't delete any browser history or anything and I haven't edited any settings. I have found this out:

It may have to do with the new version of Chrome Firefox, IE, and Flash.

Someone with the same problem: Shared object files no longer saving in Chromern
In the forum this is mentioned:

Flash Player 10.3 integrates control of local storage with the browser’s privacy settings in Mozilla Firefox 4, Microsoft Internet Explorer 8 and higher, Google Chrome 11 (Available in Chrome Dev Channel), and a future release of Apple Safari... If you clear your history and you tell the browser to clear cookies as well, Flash LSOs will be cleared. If you clear your history but you don't select cookies, Flash LSOs will remain on the machine.

But the same problem is happening to me, the .sol files aren't being stored in the first place or the loss of data is happening when I restart my computer. I'm not clearing any cookies, and I don't not have the option to clear browsing data when the browser is closed off.

This link www.kongregate.com - all-my-saved-games-are-gone mentions the someone else with the same problem.

No one seems to have the correct answer.

what if this is a security issue? what if it is a bi product of hacking?
