I have no idea how that happened I was only editing two houses in a tiny section at the top left of that bounding box. JOSM did warn me and I made sure the edit was actually only on a small area.

Hi, I've removed many duplicated highways. Please don't place a highway on top of an existing highway asit disrupts routing.

Fiction removed.

Fiction removed.

Duplicated sections of highway removed.

Hi, Welcome to OpenStreetMap.

I think that building is two semi detached houses. I've amended the building outline. But which one is Seaview? I've tagged the names as I think they should be with Seaview to the east, could you please confirm this? Secondly is Seaview a holiday let cottage?

Hi, I've removed some duplicated sections of highway that you somehow added.

Hi, the section through the gate and lightly wooded area is a highway which looks like it is accessed for agricultural or livestock purposes.

Hi, Welcome to OpenStreetMap.

Your new area would not be verifiable as formally named name=Home Area. it could be as per the other tag a description=home Area.

Unfortunately the landuse=residential area is within an already mapped residential area (Way: 44928988) way/44928988#map=17/51.544536/-0.194139

Thus I've removed the duplicate area.

Regards Bernard.

No need to delete this. I've tagged it as agricultural.

Hi, Again on the ground features are OK in the OSM database. The wooded area The Sandhills - Open Access Land (279300967) is as tagged an area that is designated to be open to the public on foot as per the CRoW Act 2000. Please see here:- https://naturalengland-defra.opendata.arcgis.com/datasets/Defra::crow-act-2000-access-layer/explore?location=52.702595%2C0.745581%2C15.50

I've reinstated these deleted features.

Regards Bernard.

Hi, Welcome to OpenStreetMap.

The tracks and paths you've removed can be seen on the ground and on aerial imagery. Thus they are verifiable features and appropriate for the OSM database. I've reinstated them all.

Regards Bernard.

Several duplicated highways removed. If a ways needs correcting please correct the existing way, don't just map on top of it. Duplicated highways can disrupt routing, thanks.

That's not a motorway, I've removed it.

Hi, Welcome to OpenStreetMap.

This footpath is a Public Right of Way and is currently open for use. There is an overlapping zig-zag gap in the central barrier for foot use on the A14. The state of the path nor the user's expectation does not alter these facts. If you don't feel safe on any highway don't use it, report it to the Highway Authority.

I've amended the tags.

Regards Bernard.

Hi, The apartments would be parts of the main building tagged as building:part=apartment. They should also have a level=? tag, could you please add this or let me know, I'll add them

I've made amendments.

Regards Bernard.

Thanks, sorted.

Hi, Welcome to OpenStreetMap.

That building looks like two houses. Do you need help with it? If so what is the other number and is 39 the north or south house?

Regards Bernard.
