Hi there,

This changeset duplicated 27 buildings. The buildings are on Greycoat lane, one of the ~7 is: https://www.openstreetmap.org/way/1239899403#map=19/42.66627/-82.95801 and Lehr Drive, one of the ~20 is: https://www.openstreetmap.org/way/1239899396#map=19/42.65969/-82.92572, and this corporate building https://www.openstreetmap.org/way/1239899402#map=19/42.66887/-82.95396  The editor warned you of this before you saved the changeset, in the future you need to always pay attention to those warnings, so you do not add bad data to the map. Please fix these, thanks!
