Ignore the whining Sheepy, you'll never be able to please everybody (especially in game where a lot of people really like to express their opinions). the game was hacked, so long as this rollback will prevent future intrusions I'm happy and i'm sure most people would rather have lost 5 days and still have a game to play rather than not rolling back and having the game repeatedly hacked because that's what would actually make most people quit.
Thanks for your hardwork getting it back up again
