@jingsam could you please provide some more details on the issue? Could you please provide some data and a code snippet that replicate the issue so we can take test it?

• [ ] GeoJSON data as a gist file or geojson.io (filename extension must be .geojson).
• [ ] Snippet of source code or for complex examples use jsfiddle.

I have the same issue, here is an example: before : http://geojson.io/#id=gist:mmomtchev/eb8c16374613397f3a0d6323cfb594b0&map=6/49.246/-1.923 after : http://geojson.io/#id=gist:mmomtchev/9d1f6a1138b4c96ebe37ee83cb8a96f7&map=6/48.320/2.010

this is with bezierSpline with 10000, 0.85

I was able to greatly reduce the frequency of it appearing by segmentizing the lines and then simplifying them before applying bezier

This is a problem that still exists for version [email protected] Test: https://jsfiddle.net/devfzm/12zbspqk/2/

Line intersects automatically after MultiLineString is offset by lineOffset

{
        type: 'FeatureCollection',
        features: [turf.lineOffset(mapData, 300, {
          units: 'meters',
        })]
}

How can I share GeoJSON?

[JamesLMilner]

You can share GeoJSON like you share JSON in GitHub comments; using three backticks and then writing json, pasting your formatted GeoJSON, then closing with three backticks again:

It renders like this:

{
    "type": "Feature",
    "properties": {
        "name": "Coors Field",
        "amenity": "Baseball Stadium",
        "popupContent": "This is where the Rockies play!"
    },
    "geometry": {
        "type": "Point",
        "coordinates": [-104.99404, 39.75621]
    }
}
