Please don't add test data to the live OSM Server.
If you want a test server, perhaps http://api06.dev.openstreetmap.org/ would work for you?

However, I reverted your changeset: changeset/72904149

Hi Brady Harwood, welcome to OSM.

Well done, your first edits does look good.
I only did a small correction of your building, because it was not square.
In the case you're going to map more buildings, you can find a help page about how to do this here: https://learnosm.org/en/hot-tips/tracing-rectangular-buildings/

Hi Atakua_imports,

I'm not sure, but my tool reported almost 1,000 way intersections for this changeset. Is it possible that same or many ways do not share common nodes or intersect? Thanks.

E.g. these two ways:
way/709310320
way/709311343

Thanks for your answer.

Comparing the removed buildings with the new ones, for me, in many cases it looks like you just deleted and redraw (moved) the same objects. Please, don't do that, it deletes the history. Thanks.
See osm.wiki/Good_practice#Keep_the_history

Thanks for your answer.
