Whenever I get a basic book, the icon is a keyboard. Whenever I get a Book of Morph, it's a picture of my character's face. This error seems to be from 2.5x...

Bug me if you want to play a game.
That used to happen in modules where the book object didn't exist, so my guess would be that Zefz forgot to make the book objects read from the new folder in basicdat. Or something?
