After some complaints from various members about random games not submitting scores and some experimenting I found this out. If you are playing a game, or go to a game and before playing leave that page, such as viewing the highscores, and then press the Back button in your browser to return to the game and play, the score will not be saved and you get this error.

What makes this worse, is when you get the error, there is a 'Go Back' button. If you return to the game using this button the error happens again as this is the same action as using the Back button in the browser.
