Unfortunately the mooring sometimes disappears. Once reported it is replaced as soon as possible. The Chikuzen was hit hard by Irma, the bow section and the holds are now just twisted metal, the stern section survived because of the engines. It still attracts a lot of marine life. Also note that the section of the wreck that survived it about a four minute swim from the mooring. Always use the mooring, at the bottom follow the rope, which takes you too the anchor line, which takes you too the wreck. Remember to play it safe as you are a long way from land and do note it can have a strong current occasional.
