Wesley's Tool-Box

If you're playing Simpsons: Tapped Out game (iOS / Android) on your spare time like me, and also happened to be a developer that upgraded your phone to iOS 7 (beta 1), then you may encounter a bizarre bug where you automatically get login to a completely random, but different account.

Some leafing through the web yielded some clues on what was likely going on. It seems to be caused by the way EA implemented the device and account management.

Apparently, EA decided to keep session information of both the device and the account that it's logged in on the server. When a user exits the game and comes back, the game checks the device and automatically login to the account it was last associated with. Seems harmless, right?
