Last weekend a party reported some new unstable boulders over the crawl just after the duck. Yesterday (2nd July) three of us (cpc / uwfra) went for a trip and spent a couple of happy hours rearranging the boulders (some of the larger could be rocked easily with one hand). It all seems stable now, with a new line about a metre to the left. The original crawl is where the boulder in the middle of the picture is.
