For the past few days the server is unable to connect to give rewards. In Grub Guardian it tells you this before playing because it cannot connect to your player. In Trivia however, it doesn't tell you until you have already done the quiz, so it counts as a play without giving rewards.
I am still getting trivia rewards even though I occasionally get this error message. Check your crowns history. As for GG, I haven't been playing that recently so I'm not sure what is going on there.
7/7/16 EDIT: I'm getting the error message more and more. It's now to the point where I can't see the results screen for many of the quizzes, including state animals. I help to maintain a database of trivia answers on Legends of the Spiral and this is getting in the way. PLEASE somebody over at KI look into this sooner rather than later!
