My girlfriend has an Android phone and plays Candy Crush Saga. She was level 140 on her phone and level 20 on Facebook. Both game states were not connected!
However, she decided to connect her Android candy crush with Facebook, which synced the Facebook state of the game to the phone. She is now level 20 in both states which is pretty sad.
How can we get the game state back to level 140?
Disconnecting from Facebook did not solve the problem.
I don't think she backed up her phone at any point.
