The Dink Network

I have downloaded version 1.08 and I found a bug! When in Mirkwood forest, when you go up so that you can get into the backyard, you go left and you see the backyard, Dink then sais: ''what a lovely backyard''. When I try to enter the backyard I am supposed to dissapear for a fraction becuase the trees block the view but instead of that i cant go forward! When I walk forward something inviseble is blocking it as if there where a wall. I know its not the angle because all my spells crash into the wall too. If this isnt a bug can someone explain how to get past it?
