Okay so on a server a friend set up (bukkit) I found a few enchated books in dungeons. I went back to apply one or two to my sword and it's not working. I tried them out on other tools and that didn't even work. It's a Power 3 book. Would anything with bukkit or plugins be the cause of this? Or a vanilla bug?
