Hello. Thanks for mapping.
You know that you did not tag 17 buildings out of 163 buildings you mapped ?
Don't you use the building plugin ?
When you use this, it automaticly  square the building you map and tag it. You can also map fine round buildings with it.
Here is the link,

Best regards and keep mapping
