Unfortunately, you dragged parts of Lansdowne Hill and Lansdowne Wood Close onto a non-existent junction with Prioress Road in your edit.

I have reverted the entire edit in order to restore the geometry of the road network. I've also restored the houses you added, retraced them and tagged them as semi-detached houses.
