Had an issue recently, and it might be from the latest patch. A lich statue magically disappeared. If you have a castle and place items on the north side courtyard steps be careful if you stack items. Had "A Decorative Plant" (red poppies), "A Decorative Hops" and a lich statue on one step. Looks like it took out the west most tile, east tile has same setup but was not touched. I wonder if it may have been one of the older "liche" statues instead of a "lich" statue. Anyways heads up if you lock down any high end items on your steps.
