Hi,

When exporting a PDF of a map using tiles that are larger than 256x256 ("Retina" tiles), the output which looks fine on-screen looks like a jigsaw puzzle on the PDF.

You can replicate that using the URL template: https://a-naturalatlas-tiles.global.ssl.fastly.net/topo/{Z}/{X}/{Y}/[email blocked]

Also a suggestion - It should be possible to use "random server letters" in the URL for faster loading. i.e. the above URL would be:
https://{S}-naturalatlas-tiles.global.ssl.fastly.net/topo/13/2396/2985/[email blocked]
Where {S} is a random one of 'a', 'b' or 'c'

    I see part of the URL was blocked as it looked like e-mail. It should be "t{at symbol}2x.png"

    It works fine if you omit the @2x in the URL, although that doesn't look as nice on the screen. I'll take a look but it may be conflicting with my own internal layer templates in a way that's not easily resolvable.

    Custom layer requests get routed through caltopo.com rather than going directly from the browser to the layer URL, so random letters in the URL wouldn't actually improve loading speed.
