So recently I went back to the books where I hadn't completed all the side-quests and started to do them. I had been using Pirate101 Central's quest page to help me find them all and make sure they got done. Unfortunately, the page for Book 12 side-quests is incomplete. After doing all of the quests listed on there, and one additional one I found in Subata Temple, I still have not received the badge. So, does anyone know where I need to look to find this missing quest?
I went back and looked for side quests after I did the main quest. The side quest badge is Hero of Subata. I missed only one quest which was in the wai no shrine that was only available after you complete the mooshu main quest.
