Bug: When playing in Free Mode in Chapter 3, "Azog the Defiler", if you skip the cut scene that shows Azog killing Thror, the next area where Thorin is supposed to battle Azog will not only show Azog completely missing but, none of his fellow Orcs will be there either. It will be a completely empty field. To make sure this doesn't happen, the entire cutscene must be viewed.
