Generated vector tiles are not so precise as geojsons #229

Hi, I have a problem with generating vector tiles from geojsons. After moving to vector tiles, the data on a map is a little different compared to geojsons. Here are screenshots with differences: diff1

diff2

I used tippecanoe -zg -o OUTPUT_FILE --no-tiny-polygon-reduction --no-line-simplification --no-feature-limit --no-tile-size-limit --extend-zooms-if-still-dropping INPUT_FILE

and here are geojsons used to generate vector tiles cable-lines.json casing-pipes.json casing-pipes-supplementary.json

could someone help, I probably used the wrong parameters. What are the best to achieve the best precision?
