The Mall Is Griefed! I think It Is Griefed When BrianahRama Account Was Hacked, And I Think It Should Close For Maintence, Here Are Some Screenshots.
Yesterday I was checking my shop, and all item frames were gone. So I believe that this is not grief, rather some bug.
I thought that Item Frames were tile entities... apparently they are not. Sorry about that, Only 1 item frame will be left per chunk now :S. I'll try to have the mall fixed up
