Well this isn't like the cover-up of the fact there was never a Moon landing, if you email EH and ask them if it has moved they'll tell you.
I don't need to be told as i can see it with my own eyes, I know, as do lots of others that can see it, we'll just wait for EH to admit it in the next few years [they'll probably blame people's feet not all the tunnels], can you not see the change yourself?
