Sat_Taehyun. May I know the reason why did you delete this "natural=wood in this changeset?. See http://overpass-api.de/achavi/?changeset=45877713 , according to the imagery exist a natural = wood. The correct edition would have been to improve to the imagery satellite.

Hi Oba510,
Thank you for letting me know about this issue. These streets were added on the basis of Tiger data. However, the JOSM filter was on and I failed to notice the `landuse=construction` tag areas, since they were hidden. From now on, I will make sure to avoid adding any data in the under construction landuses. Thanks again.
Best,

Hi andrettis. May I know the reason why did you delete this buidling in this changeset?. See http://overpass-api.de/achavi/?changeset=43606593

Please can you fix this impossible oneways at this intersection: node/3418939064/history?

That's strange, you could download many cases of 'Self intersecting ways' on # to-fix: https://osmlab.github.io/to-fix/#/task/selfintersectingminorhighwaysjtma or on Josm-tofix-plugin: https://github.com/JOSM/tofix and try again the validator's performance. Also feel free to ask us any questions in this issues : https://github.com/mapbox/mapping/issues/203

I also wondered the same about it, and after an inquiry I rectify myself in my comment mentioned above. Really this error was detected on the #to-fix task : 'Self intersecting highways' but in an involuntary neglect I uploaded my changes with a comment of #to-fix task: 'Unconnected highways'.
Thanks again for your feedback,

Hi Hjart,
I fixed an error type of 'Self-intersecting ways' and #to-fix has detected as a disconnected road or junction .According to wiki: osm.wiki/JOSM/Plugins/Validator this type of error is not correct for the validator. Perhaps there were several ways to solve, but I opted to split at the intersection of ending point. I hope I haven't affected your previous work.
Thanks for commenting about my edit,

Hello Littlebtc, I'll look it right now. Thanks for your notificatión.

Hello rickmastfan67!
Thanks for your notification. This will lead us to wonder if the #to-fix should consider as an error the turn lanes "none" added by mappers. I've already reverted my changeset: changeset/39964115.
Thanks again, such feedback helps to create better checks in the system to maintain the high quality of the map.
