Today I started decorating my new Watchtowr Hall. I put a shelf up on the wall, one that you buy from the housing merhcant in Northguard. Then I put a book on it. After that, I tried to move it around, but the book stayed stuck in the wall, while the shelf moved. I can not click on the book to move or turn it.
Is there anyway to fix this (besides picking up everything)?
It sounds like the game is treating it as a painting.
Try moving the shelf away and then moving the "book".
In any case, you should send in a ticket to Support, describing the problem, the exact name of the shelf, and the exact name of the book. Bringing the problem to KingsIsle's attention by submitting a detailed bug reports is a good way for us to get things fixed.
The book that got stuck in the wall was "Traps and transformation." When you first enter the Watchtower Hall, the smaller room immediatly to the left is the room. On the same wall as the entrance door.
