Meadow is the correct designation here, as per the wiki: osm.wiki/Tag:landuse%3Dmeadow
It is reasonable to default to farmland when unsure but this is clearly grazing, as you can observe the animals etc in imagery

There is clearly some sort of track on recent Maxar imagery. I don't recall why I tagged it as service road, perhaps the dark colour suggested asphalt but it may be a simple track

I have removed them from the relation.

Hello, thanks for spotting this. I do not know how they came to be included as I don't recall touching the Saint's Way relation here.

Hello Andy, thanks so much for fixing that.

Didn't show it on that occasion, I can't think why

I don't recall one and I have a GPS trace from running it but with the tree cover it maybe isn't accurate enough. The original line was on the wrong side of the stream. I will run it again in a couple of days and try to get a more accurate measurement

Oh I see, different changeset. Fixed it. ID editor did something unexpected there.

no changes to relations appear in the changeset

Thanks for that I'll take extra care in future to check the edits with big multipolygons before committing anything

I didn't intentionally remove them. I don't know why josm would remove them simply through adding an inner way with 'update multipolygon'. That multipolygon though is a monstrosity which includes areas that are definitively not Bristol

Apologies, I have reverted the changeset in that area. Assumed they were part of the old yahoo traced stuff there that gets the validator angry if you touch it.
