Something is wrong with this changeset, as NSE is not ready yet and thus no way that the highway left construction phase.

In terms of relation, it will be preferable to just use another role (i.e. construction_stop) instead of role (stop) for the member node instead of deleting the node from the relation. By deleting off the node, it makes maintenance of such relations difficult.

The node itself is already tagged with the construction tag so no issues with that.

Hi,
I don't think there is a need to remove the stop node even if the station is still under construction, because the node stop itself is already marked as under construction.

Hi,
Can you stop spamming parks where it doesn't exist? If it is not defined as a park anywhere else, it is not a park and at most a grass patch.

Hi,
Can you double check if the postal code is correct? It appears that the previous postal code seems to be in order.

Hi,

For consistency you may want to tag the building with addr:neighbourhood instead of name instead.

Hi,
The station entrance should not be mapped as the train station building, as the train station consists of all the linking tunnels and concourses.

I would suggest ignoring the building in building validation. The validation doesn't really work well for building complexes with multiple addresses.

More importantly, places with addresses should be correctly tagged and searchable, else the POI information will not be useful.

Hi,
This changeset corrupted the 3D building parts for the building:part at...
osm.org/way/440538817

In addition, changing the from building to building:part also lead to the building address not being searchable in Nominatim.

Hi,
You may refer to the following building outline.

Hi,
Your addition of building heights for Harbourfront building ignores the building parts (and the various building levels) that already exists for that building, and will overlap with the 3D building parts.

May I suggest that you double check on this?

Thanks.

This changeset introduces lots of incorrect access=no tags on nodes of a way.

Suspect user highlighted all nodes and ways and applied access=no to both nodes and ways, instead of applying it to ways only.

Hi,

There's a grass field over multiple residential blocks. This is not accurate.

OSM is a data source that is not purely for games only. Please be responsible and do not input incorrect data.

Thanks.

Hi,

There is something wrong with the park drawn as the park definitely should not cover any buildings.

OSM is a common data source that is not purely used for games. As such, I would advise to revise this change so that the things are tagged correctly.

You may want to use JOSM with the reverter plugin to revert this. Alternatively, I can help revert this change.

Why is the 3D building part deleted? The floor counts are different.

Hi,
There is no hard rule whether the road should be mapped split. However, enhancing roads to be split does improve ease of mapping bus routes as it allows editors to automatically optimise the path segments.

There is thus no error since the it is simply a greater level of detail.
