How to fix the additional content bug

I just got this game a one week ago, and it was very fun! But two days ago I cant get into the game with Internet because of the "additional content" glitch. Many people write reviews about this glitch, and I found a way to fix it! So here is how you do it on iOS.

1. Make sure you are connected to your Game Center

2. Delete the game

3. Download it

4. If you have a Game Center account, it should ask you do you want to connect to your Game Center cloud account of this game

5. Boom! Connect to the cloud account and you got everything back!
