I can only identify two buildings here. The building you repaired is only about 4 m² in size. I switched back and forth between Bing and Mapbox imagery to get a better picture of the situation. Most of the errors addressed in this Maproulette challenge are typical beginner problems. When looking after these problems you will always find more issues nearby. A good pointer for areas that need a lot of rework. So please be careful, to not only obscure other problems, that are much more difficult to detect automatically.
