Game-wipe scare, but its all good.

At first, I thought this update deleted all my game data, but it just logged me out of Facebook. Logging in again restores data. For those who did not log in to Facebook, this update may well just reset all your progress. Be warned.

Other than that, the two new power birds are super cute, and perfectly appropriate for the season. Now I have a reason to start playing again - to collect these limited edition birds! XD
