They are working fine if you delete game data and all save data, reinstal game and start a new charactor. If you don't want to do that then don't complain that they are broken cause they are not.
Not true.
You don't need to start a new character at all. Mine fixed just fine.
The problem I am quite certain is that people are not understanding that there are two seperate types of bookcase issues. One where they never worked in the first place and one where they work but when you put books in, they mess up.
The latter is what they fixed.
Once your save file is messed up, it's done for I think. The shelves that never had books on them will work now, but if you have stuck books, they may still be broken.
