Publisher EA has temporarily removed The Simpsons: Tapped Out from the app store due to issues relating to the connectivity and lag issues. It is believed to be affecting the iPhone, iPad and iPod touch versions of the title.
In response to a question on the publisher's website, EA stated the following: "To ensure current players have the best possible experience, we've temporarily removed The Simpsons: Tapped Out from the App Store to limit the game's server capacity to its current players and address connectivity and lag time issues.
"If you've downloaded the game, you can continue to play. Actually, your experience should only improve as we work on a solution. As soon as we have resolved these issues to handle greater player capacity, we will return The Simpsons: Tapped Out to the App Store so that even more people can enjoy this "life-ruiningly fun" game.
"Meanwhile, thanks to everyone for their patience, and we will provide an update as soon as we have more information to share."
There is no re-release date for the game, but hopefully these fixes shouldn't take long to sort out. Anyone who has the game should still be able to play it, hopefully with much less trouble now.
