Oh ok! I thought that for Ada county all addresses were supposed to be added as nodes.

Makes sense, don't know why I added it like that! Fixed it. changeset/108989895

After looking at the wiki, I see that I was completely wrong on what an apartment complex is, is there a way to revert changes or do I need to add it back manually?

Oh I see them! Sorry I don't check my email often and I assumed that if someone commented on my edits it would show in "My Messages"
