When you are at the point when you need to do the Cavern of the Crescent moon dungeon, when you log in and go on to the player, Ratbeard says "...but the King and Queen betrayed us." instead of something else the text says. Sorry I can't remember. This happened the 2 times I logged in and the time a friend logged in so I am not the only one.
Hello and thanks for your report! There does appear to be an issue with Ratbeard's lines when on the Quest The Monkey's Paw. We'll take a look at getting this fixed in one of our upcoming updates to the game.
