We're excited to announce that we've fully migrated the Xbox Forums to their new home, here on the Microsoft Community forums!
As of today, going to forums.xbox.com will redirect you here to the Xbox area of the Community forums. We've moved all of your existing threads over so you can continue and start conversations with the new forums experience.
We sincerely appreciate the feedback you have provided over this transition and can't wait for you to check out the new Xbox Forums!
A lot of the times, Games and or content is removed from the marketplace due to Licenses expiring or changing hands of ownership. Right after the holiday, I noticed that all the Harry Potter Avatar Items (save the lego stuff) were completely off the market
for some reason. These things happen. All you can do is keep an eye on the market place for any changes! :)
