Hi friends;

i have been playing this game for 1 week; i love it so much. But not i have a problem and can not find a solution. I was playing this game in my android mobile to yesterday. I connected it to my friend FB account to check what will change But now i can not delete/ disconnect this link in game. I want to continue to play in my android mobile phone and disconnect its connection with Facebook. How can i do this? As i dont use FB and connected the game to a friend of mine facebook, need to delete this link and continue to play in my mobile.

Thank you su much.
