tippecanoe -z3 --no-tile-size-limit --no-feature-limit --no-simplification --no-tiny-polygon-reduction -b127 -c 'mkdir -p output/$1/$2; cat > output/$1/$2/$3.ldgeojson' /Users/enf/Downloads/RhodeIsland.ldgeojson -f -e output

The coordinates in output/0/0/0.ldgeojson are like [ 108.281250, 41.836828 ] instead of like [-71.822269,41.368928]. Overflow in the longitude somewhere? Doesn't happen without the large buffer of -b127.
