In 'Forgettable Tale of a Drunken Dwarf', when the drunken dwarf gives you an item to fetch, your guide says that if the item is bad, you can log out, then back in again for another assignment. This doesn't happen - he remembers what he wants. What a drunk dwarf would want with a fake beard I do not know! If it doesn't happen for you, then I play on the UK servers, so maybe that has something to do with it?
