I don't know how long it has been like this, but all of my castle blocks have been stuck in place, possibly since the spring update. I didn't notice for a while, until I tried moving some of the blocks that I had stored in a dorm room and they wouldn't move. All of them had been placed before the update (which included introducing advanced move which might have caused this problem). When I click on any of them (over all of the houses of all of my wizards on my account) the "move" and "pick up" buttons are grayed out. On my characters that can use advance move, they can be advance moved, but they can't be picked up. I tried picking them up in the house part of the attic, but while the button lights up, nothing happens and the castle block remains where it is. So there is no way for me to get them out of the houses they are in. While this isn't a huge problem, I don't want them stuck forever. They aren't always easy to find in the bazaar and they take up a lot of room.
