Looks like the second to last hold for Amphibian Conceit/Hitchhiker has come off. I think it has been left on one of the foot holds near the base towards the left. It looks about the right shape anyway.
I wouldn't have the first idea about how to glue it back. Just thought I would let people know incase someone with the expertise cares enough to fix it.
Is there anything I should do with the presumed broken hold? Leave it there, take it home etc
