Interesting. I can't see a single bookshelf skill in the pulldown menus. The relay browser has no problems showing them. That is I can not chose Snowcones, Brickos, Hilarious stuff, candy hearts nor sugar parts to summon in the graphical interface.
The same is true for when I login, the breakfast never casts nay breakfast tome-dependent skills no matter what my settings are.
Currently using 8320, but it's been this way for quite a while.
