This bug occurs if you start a new character or load a save from before you enter the shadow-cursed lands. Using a save from before patch 5 where you had already entered the shadow-cursed lands let's you see the old version. The problem seems to be that Mol never hops onto the chair next to the lanceboard and gets stuck on the way there instead.
Astarion's bit with Raphael is also bugged out here since you can ask him about his scars as if you had not seen them before, even if you have.
