Hi, babyranga. I've friended you back, if that's how it's put over here, and you may want to check on Chapter two of the game. That's the one I, and a friend of mine, don't have the required 18 stars in. Neither of us have the Dragon Tower and if it takes 18, I'm guessing that's why. I didn't know prior to today, that you had to have 18 to get a wonder.
