I'm trying to put together a bookshelf, and testing has shown that it is acting very weird.

I've been following this guide: http://www.creationkit.com/Tutorial_Bookshelves

I've gotten as far as "Adding the Triggers" but not as far as "Containing the books" because I want to make sure everything works before I duplicate it to fill the other two shelves on the bookcase I'm using, after which I'll add the collision cube.

Anyway, what's happening is that when I take a book off the shelf by clicking on the book itself (instead of opening up the shelf's inventory) the shelf's inventory size grows by one book. Right now I have 16 dummy books on the shelf, each with linked refs to the container. When I take a book off the shelf without going through the container's inventory the number of books that will "fit on the shelf" grows to 17 books (though only 16 will ever show on the shelf). I can even make the inventory size grow past 18 books, which is supposed to be the maximum number.

Another strange thing is that it places the books on left to right, and then takes them of the same way without moving everything back over to the left, like how the shelves in the built-in houses work. This isn't a big thing; it's just a bit odd, and I was wondering if this is also a bug.

Anyone know what's going on here?
