Missing terrain tile #193

There's a missing terrain tile in the East Bay at zoom level 8

Issue does not show up in live interactive Nextzen maps that we've pubbed

Zero idea why, but this issue disappears when the tiles are fetched as GeoJSON:

nextzen:
        type: GeoJSON
        url: https://{s}.tiles.nextzen.org/tilezen/vector/v1/256/all/{z}/{x}/{y}.json
        url_params:
            api_key: global.sdk_mapzen_api_key
        url_subdomains: [a,b,c,d]
        rasters: [normals]
        max_zoom: 16

Any disadvantage of handling this way?

The above solution actually results in a new bald spot above Chico between zooms 8 and 9. What I ended up doing was adding a GeoJSON layer ONLY for the earth tiles and including a MVT layer on top. That seems to cover all tiles.

It's a bit slower to download both file types, but it's filled in and and exports well.

That's really weird. I think it must have to be an error in the YAML style file.
