Ok, this is ludicrous. I just went from beginning to end the irritating process of clicking castles of any person to collect the gold. Tested this theory and then restart your browser. When you reload the game had lost more than 750 gold. Mobile DAL checked to see if gold had returned to a state without charge, and it was not. This is bigger than a sync error. Gold is simply disappearing. (I've never lost the crown in this way; I think it's just gold.)
