I can't be the only one who has this happen on a regular basis, can I? When you leave a game, go get a cup of coffee, and come back you find a big red error: "Error page Game is already over." (Assuming you have auto-refresh on)
This is because, for whatever reason, leaving a game redirects to http://arcomage.netvor.sk/?location=Games_details&CurrentGame=[gamenumber] rather than just http://arcomage.netvor.sk/?location=Games
