Overpass complete conversion is not working as expected

[HarelM]

I have the following code:

        var response = await GetQueryResponse($"[out:xml];\nway[\"highway\"][!\"construction\"]({southWest.Y},{southWest.X},{northEast.Y},{northEast.X});\n(._;>;);\nout;");

        using MemoryStream memoryStream = new MemoryStream(Encoding.UTF8.GetBytes(response));
        var source = new XmlOsmStreamSource(memoryStream);
        var completeSource = new OsmSimpleCompleteStreamSource(source);

        return completeSource.OfType<CompleteWay>().ToList();

This should get from overpass a list of highways that are not under construction in a given bbox.
The response from overpass is working as expected and I wanted to get the version of each highway.

When I use the OsmSimpleCompleteStreamSource it is not working as expected for some reason.

The following code is a workaround to overcome this, but I'm not sure what I'm doing wrong:

       var query = $"[out:xml];\nway[\"highway\"][!\"construction\"]({southWest.Y},{southWest.X},{northEast.Y},{northEast.X});\nout meta;\n(._;>;);\nout;";
        var response = await GetQueryResponse(query);

        using MemoryStream memoryStream = new MemoryStream(Encoding.UTF8.GetBytes(response));
        var source = new XmlOsmStreamSource(memoryStream);
        
        var db = new MemorySnapshotDb().CreateSnapshotDb();
        var list = source.ToList();
        db.AddOrUpdate(list);
        return list.OfType<Way>().Select(w => w.CreateComplete(db)).ToList();

When I debugged the OsmSimpleCompleteStreamSource it seems that the cache is empty after Seek is called, which I wasn't sure it the expected behavior.

Let me know if there's anything I can do to help here.
