So sad to hear that.
Here's from BFS FAQs:
My game started over from Level 1 and I lost all of my progress! How can I get back to where I was in the game?
This can happen if you had to change your AppleID password, updated your iOS, were required to agree to new Apple Terms of Service, created a new Game Center nickname, or logged out of Game Center altogether.
First, open the Game Center app and make certain you are logged in to your Game Center account with the same account under which you were previously playing.
If you need to retrieve your Game Center password or account information, please contact Apple support as we do not have access to that information.
If a technical situation requires a park transfer we will do our best to accommodate. But in general we do not perform park transfers.
If you are still having issues, please email us at
[email protected]. Please be sure to include your Game Center nickname in the email.
