terrible alignment - Esri imagery is clearly not well aligned here and you need to deal with this whenever you edit

One issue with junctions that are 'turn off to stay on' (in this case the A4), is that the choice if which ways are link and non-_link can be reversed from 'normal'. I would have been tempted to allow routing along the A4 in both directions to stay on the A4 (non _link), which is not the case as mapped here (affecting the choice of way type and ref for 3 of these way segments)

The changeset description fails to mention the 'forest' and grass areas also added in Halifax NS.
Please make changesets that cover a single area, this is smaller than many of your previous but still spans 1200km.
Also, if you're going to add buildings, please use the tools provided by the editor (eg shortcut key Q) to square up the building where appropriate - nearly always) and avoid kinks, cut corners, 5th nodes etc.
And please make sure parking areas etc respect buildings.

This change left the residential area N of the railway (basically the whole of Derby) as an unclosed loop (and part tagged with hedge due to ways merged). All repaired.

From the distinctive shape it looks to be the building that had to be redrawn in changeset/72442081 (as new way/705808402) as the original had disappeared from the correct position as originally drawn here.

Seems to have had its coords modified (obv lat+long, also scaled down by factor of ~5?) by some unintended action in changeset/43980969
(see the v2 of the 12 nodes 4517234xxx)

So seems it can be deleted.

Apparently the app's project page on github is the place to request such things, so I've raised an issue there for this (along with supporting a previous issue to move razed/dismantled in the opposite direction), see https://github.com/osmandapp/Osmand/issues/8832

In OSMAnd, rendering preserved rail (except at very close zoom) seems to be regarded as an optional 'detail' - not good. If you go to the OSMAnd menu: Configure Map - select the required map mode global/car/bike/foot etc (separately switched for each) - scroll down to Details - turn on More Details, then it shows. This is worth raising at https://groups.google.com/forum/#!forum/osmand
A search there brings up one comment from 2018 with no reply, I'd support re-raising that there (and returning this rail line to be tagged as it should be).

All reverted back to as it was. Yes, the upload in JOSM saves all changes to the main map. Also worth noting that objects (nodes, ways etc) have a useful history so always good to edit the existing object (eg shape of fairway outline) rather than deleting and creating anew. Have another go.

Looks like you had the residential area (for whole of Dingle) selected when you added the new post office tags. Should be fixed ok now with the just the correct building tagged as post office.

I've reverted this changeset as a section of Hawksley Avenue, and also a short section of Saltergate, got dragged sideways along with ways connected to them, see https://overpass-api.de/achavi/?changeset=79581556

I can't see what change was intended (changeset comment refers to post office??) so any intended change would need to be re-applied, regards Cebderby (Clive)

Reverted. Do not delete information from OSM.

Bad change, was correct as exit only.

Reverted. Do not destroy data from OSM, both roads' oneway-twoway change points were accurately mapped.
