I left the book Kodlak's Journal in my Breezehome, sitting top of the bedroom dresser upstairs. However, upon next inspection of the area after leaving and coming back, the journal was gone. I didn't think this would happen since a purchased home does not respawn items. Is it simply somewhere else in the house, and I need to search for it? An answer from this question by BoseBorre leads me to believe the journal has been moved to a random location somewhere inside.
If this is not the case, what happened to the journal?
