Suddenly in the game #7, the alert "Make your opponent resign" appear on the screen (I was playing againt Lord Rattington). Clicking Yes make him resign. But Why this alert appear in the game (it was during my turn and it was a long turn so no activity for the bot, may be a clue).
I had the same issue. Game #10 on frankfurt-test, also against Lord Rat.
game #13, same message. I didn't click on "Yes" the message come back every 5 seconds ....
