We were at the Chosspile today (Saturday 28/11/09) and found that the left chain at the top of GRIFFENDORE at the Harry Potter Wall was missing a nut. I abseiled down from the right remaining chaining and placed a mallion on the last hanger for additional protection. Unfortunately while abseiling the left chain fell off its bolt so I have placed it at the bottom of the climb (not having a bolt with me to secure it myself). Maybe someone with the know-how and a spare nut could replace the missing chain on their next visit?
Also, on the 16 to the right of GRIFFENDORE there is a hanger missing from the 6th bolt up leaving a vast distance to be covered from the 5th to 7th bolts.
