natural=mud appearing later than natural=sand/beach (z13 vs z10)

[malcolmh]

natural=sand/beach and tidal=yes appear at zoom 10
natural=mud and tidal=yes appear at zoom 13

Note that tidal tag not used by this style (see https://github.com/gravitystorm/openstreetmap-carto/blob/master/openstreetmap-carto.style - it is skipped during importing data into a database).

[matkoniecz]

Can you give an example of place where it leads to a bad rendering?

Here there is both mud and sand areas adjacent to each other. At z10, 11 & 12 only the sand is rendered, creating an 'island' of sand. In reality this is a single, continuous tidal flat.

according to the wiki definition of the key "natural", both, sand and mud,
are malformed values and should not be used, while "beach" is fine as it
describes a geographical feature. I suggest to push moving "mud" and "sand"
under another key like "landcover" or "surface".

@dieterdreist Well, both "mud" and "sand" are currently rendered. You may want to open a separate ticket.

"not according to the Wiki" Where? On the main map features page, natural=mud/sand/beach are all documented, with the renderings that do appear. Where does it say that they are "malformed"?
The only other pages that I could find suggest wetland=* tag might be used instead, but no mention as to the renderer status of these alternatives.

[matkoniecz]

I consider this as a bug caused by #420

[matkoniecz]

#899 is next in this group.
