I love this game, just needs some adjustments

I just downloaded this game a week ago, and I LOVE IT!! Ive been so obsessed with it!! Since the new IOS update, the game has been a mess. I cant invite just one or two people to play anymore because the Game Center has disappeared? Even if I try and invite only one or two people by selecting the 2 or 3 players option, it still makes the game for 4 people. Which is really annoying when I just wanna play with family and friends I know. I really hope you guys can fix this because I love this game and if you cant, Im gonna be mad, one because I paid for the game and 2 because this game is so much fun and I love playing with my friends. So please fix it. PLEASE!!
