Description of the problem:
When I hover over one of the houses in the Hogwarts crest (top left) that's not mine, it takes me to the door of the common room (like before). However, now the door doesn't disappear by itself. I had to click on the door, which takes me to (I assume) the common room. Since I don't technically have access, the usual error message (look below) appears. But the error message is normal, since it disappears by itself. The problem is that whereas previously the door disappears by itself, now I have to go back to return to the previous page.

Screenshot:
It's hard to screenshot, but basically my computer is stuck on this screen until I hit the back button (top left):


Error message:
"Blimey, you seem to be lost, there is nothing to do here!" (Not technically an error message, since it's set up to be this way).
