The bug that I had fount in the game testing suite was in the start game when I was unable to get past the loading screen and it had stopped at around 95% on it. I then refreshed the page and the game had loaded fine.
Throughout testing this game this bug has only occurred once. I was not able to repeat it.
Was you using Internet Explorer? If so, try using Chrome or Safari, as the game would work without a problem then. Perhaps you should do that as it is buggy when using IE... I tried playing it in IE and the page just kept doing the intro movie like WTF
