I'm puzzled, because the misplaced node https://www.openstreetmap.org/node/307642733/history#map=17/51.35791/-0.26294&layers=N says it has not been edited for 15 years even though it's part of https://www.openstreetmap.org/changeset/150392876#map=4/28.18/14.63 that was edited 17 days ago. 

I see rskedghill has made a comment on that changeset and have messaged him to see if this can be undone.
