@przell I assume you mean `write_stars()`? Could you provide a reprex, preferably with the S2 tile in package `starsdata`? (see [here](https://r-spatial.github.io/stars/articles/stars2.html#stars-proxy-objects-1))

That is the result from ``` st_warp(st_set_crs(r, 4326), crs = 3857) ``` which assumes WGS84 for `r`, then creates a regular grid from a rectilinear grid in web Mercator. I...

Yes, see https://github.com/r-spatial/sf/blob/master/demo/twitter.R for how messy this can get. I wouldn't go this way until @paleolimbot and I get [libs2](https://github.com/r-spatial/libs2/issues/6) done; see https://github.com/paleolimbot/s2plot - I expect this to be operational...

Yes, this is a nice odd case for `s2`. If you switch `s2` off, by `sf_use_s2(FALSE)` then things seem to work. The geometries are then valid on the plane, not...

@dcooley ?

Thanks for looking into this! I'd like to see `st_read` succeed in such cases, best would be with a warning and a suggestion how to clean up the mess.

@dcooley any news on this one?

The purist in me would say: leave this an error, let the user solve the problem, and let the user try again after solving it. But then: how should she...

@dcooley the requirement you refer to is skipped when we come back from `CPL_read_wkb`, i.e. when we read data from file.
