Ok, here is what I suggest. We have a player make a new book, and put it in a chest.
Then we have Nick or another admin do the command to force update the live map render. Wait however long you expect the live map to take to render the map, and then check the book.
Isn't our live map plugin really old anyways? I'm going to check and see if it even renders emerald blocks yet. Last I remember, it hadn't even been updated to do that yet.
