Minecraft has been named to 'minecraftpe' and has a missing logo. Then I started the game up, and I had been signed out of my XBOX Live account and all my worlds were missing! And when I try to sign back into XBOX Live the game crashes. This happened straight after I updated to 1.2.8 and makes the game unplayable.
Thank you for your report!
