The latest tippecanoe 2.51.0 cannot produce vector tiles well

[JinIgarashi]

I am not sure this is a bug, but the latest tippecanoe does not produce tiles well.

In my local tippecanoe 2.24.0, the following command can work well.

The below is PMTiles produced by 2.24.0

nanyuki.pmtiles - tippecanoe 2.24.0.zip

``` tippecanoe --no-feature-limit --simplify-only-low-zooms --detect-shared-borders --read-parallel --no-tile-size-limit --no-tile-compression --force --name="NAWASCO Vector Tiles" --description="Vector tiles for water & sanitation data in Nanyuki Water and Sanitation company, Kenya" --attribution="©Nanyuki Water and Sanitation Co., Ltd." -o /tmp/src/data/nanyuki.mbtiles /tmp/src/pipeline.geojson /tmp/src/sewerline.geojson /tmp/src/meter.geojson /tmp/src/kiosks.geojson /tmp/src/borehole.geojson /tmp/src/tank.geojson /tmp/src/booster_pump.geojson /tmp/src/chambers.geojson /tmp/src/manholes.geojson /tmp/src/t_wrks.geojson /tmp/src/blocks.geojson /tmp/src/blocks_annotation.geojson /tmp/src/cadastral.geojson /tmp/src/cadastral_annotation.geojson 60043 features, 3120496 bytes of geometry, 666045 bytes of string pool 99.9% 14/9882/8193 /0 ```

But, in the latest 2.51.0, it shows a message like 60043 features, 3355810 bytes of geometry and attributes, 666045 bytes of string pool, 0 bytes of vertices, 0 bytes of nodes while there is no 0 bytes of vertices, 0 bytes of nodes log in v2.24.0.

The below is PMTiles produced by 2.51.0. As you can see, most of features such as pipeline, sewerline are not in tiles.

I think my tippecanoe command might have problems, but I am struggling to find a solution to fix this. I am not sure this problem is there since which version. Do you have any idea to fix the problem?

I attach geojson files here to reproduce.

Thanks for the report! This is a very strange and unexpected regression. I'll look into it and figure out what has gone wrong.

Thanks again. The bug appears to have been introduced in version 2.43.0. I'll take a look at that PR and figure out what I did wrong.

This will be fixed in https://github.com/felt/tippecanoe/pull/221
