Tldr I said delete the redundant node because I thought that would be easy to understand, user Lyx asked them to stop deleting nodes (to preserve history) and to combine them instead. These two direction conflicted so now they copy paste a "we don't know what to do" message. I talked to one of there organizers and thought this issue was cleared up. But there is a long long tail of unresolved bad edits.

I see you used "height=0" in this import, what that it mean?

Example:
way/798982168

This change pretends that there is a large building with two smaller buildings inside it which is clearly not the case judging from sat imagery. Consider asking for assistance on the #tagging channel at https://slack.openstreetmap.us/

Welcome to OSM and thanks for fixing Country Lane. Many of the roads in OSM were imported with unreliable geometry around 2012. There's a lot more to fix if you're interested. -Alex

When you move details from a node to a building, please delete that node because it is redundant. As you have this, it looks like there is a motel inside of a motel. Please come back and fix this, regarding node/4443100165

I see now that you have made this same mistake (leaving behind duplicate business nodes) in your many many changes. Please review all your past changes and correct this issue. Here is a tool which may help you do that. https://osmcha.org/?filters=%7B%22users%22%3A%5B%7B%22label%22%3A%22Riyana_Shrestha%22%2C%22value%22%3A%22Riyana_Shrestha%22%7D%5D%2C%22date__gte%22%3A%5B%7B%22label%22%3A%22%22%2C%22value%22%3A%22%22%7D%5D%7D

When you copy all the information from a node to a building, please delete the node (specifically: osm.org/edit?editor=id&node=1794437293). In this case, it looks like there is a guest_house in a guest_house?

You've duplicated the same information onto two elements. So now it looks like there are two businesses here that happen to have the same name. Please delete the node since the building has more information and more detailed geometry.
Also, you website you added doesn't seem to represent this business.

I wonder if this is still "proposed"?
way/32731550

Thanks for fixing this. WAY: 35992056 has two sharp "zigzags" in it. Do you know if those are accurate?

Hi, thanks for adding this building. I added address nodes as placeholders for buildings. When you add a building, please move the address tags from the node to the building, then deleting the address node so it isn't redundant. Regarding: node/7231419605
Please ask if you have questions. -Alex

Turning loops can be represented by either a highway=turning_loop or by an actual circle of road. I prefer using road geometry (as you did here), but please delete the turning loop node (node/6979964251) when you do this, otherwise you have a turning loop with a turning loop in it.

Thanks for adding these buildings. When adding buildings, if you copy all of the address details from an address node (like you did here), please delete the address node as it is now redundant. (For example: node/7167474260)
