You could report the bugs with the specific games on the main Bug Thread in this forum. I see that you've gotten Quests on 25th Oct though, which was the date of this thread. Sure you met the requirements for the Quests in question?
You could try relogging into AG on another kind of browser.
sometimes there could be a delay between solve and get the quest. Specially the newer quests for King of Towers and Clicker Heros could have a pretty long delay (some minutes).
