Astarion and Godey Dialogue Bug (spoilers)

[Icemax]

I am doing Astarion's quest and am currently in Castle Cazador, or whatever. I found a secret room with a Skeleton named Godey, who I intimidated, but Astarion said he was there to kill Cazador so he went hostile. I killed him easily and looted him. Later on, after exploring and looting essential items for the quest, I talked to a servant named Vilhelm, who told us about the ritual we already read about in the journals. He mentioned Godey and Astarion asked where "the old bag of bones" was, despite the fact that we had killed him minutes before. This is clearly a dialogue bug.
