Hi greece1821, thanks for pointing this out! After further investigation, I also now see that Mapillary (https://www.mapillary.com/app/?lat=40.605369173&lng=22.9713982344&z=17&pKey=746263579385735&focus=photo) confirms a continuous building footprint in between the roof sections. I have now converted this back to a single building feature, thank you!

Hi greece1821, thanks for the heads up here! I’ve removed the building feature.
