Seeing a format error in the tooltip for the Enchanted Books.

It does say that the format error is being added by Minecraft.

Thank you for reporting this issue. The Format error bit is not part of the "Added by Minecraft" text line.

This issue should be fixed in the latest build. If it is not, let me know and I will fix it again.
