It is reported to me by someone who went to the mid level at Kings & Queens to do the abseil down to Queens.
On the 1st pitch it would appear that there has been a significant change to the bolts.
1. It looks like the rock around the deviation bolt must have failed as there is only a remnant hole left and no deviation
2. The back up 3rd bolt can be rotated in its hole. The nut seems to be cross threaded on the bolt and I wonder if this has allowed for sufficient leverage to be applied to overcome the rotational resistance.
The 2 primary belay bolts look fine and there were nuts tight on the hangers.
My advice is to give this area a miss, pleanty alternatives there.
