Hello,

There is some problem in your changeset : 

- https://osmlab.github.io/osm-deep-history/#/way/246311636 you move the outline of the building. 
- https://www.openstreetmap.org/way/993055808 : you add generator to all the building, that is not the case , area =yes on building make also warning in validator, and even it's not necessery in other case : https://www.openstreetmap.org/way/1151355748 you can remove it to fix the typo. (set area is not a error but as your way are closed you don't realy need it). 

https://www.openstreetmap.org/way/263981303/history also it's not all the building with generator, and as you can see it's on a construction zone, a part of the building doesn't exist anymore. 

Can you fix the issues please ? 

Hope that can help.
Have a good day.
