I have a JSON file that tippecanoe seems unable to tile. It is a large and complex GeoJSON of polygon contours.
tippecanoe --coalesce-smallest-as-needed --detect-shared-borders --coalesce --reorder -z5 -pw --output-to-directory=out infinite.json
infinite.json.gz
Possibly related to the -pw functionality as it doesn't occur without the flag, but could be because the relevant contours are clipped without it.
