Incorrect vector tiles for zoom >= 13 for multipolygons

[dnepromell]

Some cutting of vector tiles for these 4 parcels (multipolygons). I tried with different options, but no luck. Demo page looks like not renders at all this example.

Geojson file:
ubombo.json

Zoom 14:

Zoom 13:

Zoom <= 12:

Geojson.io renders parcels correctly:

Sorry for a late response. This is likely because of polygon simplification logic — geojson-vt throws out polygons which are below a certain area threshold. It can be confirmed by passing tolerance: 0 which disables simplification.
