When you are in the Shire and have to find the Clanker, before you get it, go on the place where the bell is anyway. At the bottom left hand corner are some boxes. Pick one up, walk over to the stairs, and let go. The box will sink into the stairs.
Stuck in building
In Bree while playing as Aragorn, get the bundle of hay for the dummies that you need to make. If you save the game in the building that you get the hay in, you will be unable to leave. The entrance will act like a wall. You will not be able to continue the game.
