I had problem when I tryied to cast Renew (rank 10) which is learnable from book, it always casted Rank 9 renew. Took a while to figure out why it happened and then I realized it was autorank which was causing it.
With my uber coding/scripting skills (or not) I managed to put lvl 50 renew to script code, which fixed it (though, I hope I didn't break anything).
Just if you would like to update autorank to work with those new ranks that are learnable from books
thanks.
Very nice addon btw
keep it going.
