It is now possible to enter a custom paper width and height, so that map prints are no longer limited to the predefined paper sizes.
This can especially be useful when creating maps for different materials like textiles, customized jigsaw puzzles, etc. where the form factor does not match regular paper sizes.
As the headline says: this service has just received and processed its hundred thousands map render request.
I’m not really sure what’s going wrong with it, but apparently the paper layout is sometimes automatically switching to multi page format on submission of single page render requests, and the choice is made “sticky”, too, so the next time you create a map from the same browser multi-page layout is pre-selected.
I’ve experienced that a few times myself now, even with witnesses looking over my shoulder when it happened, but I have no idea by what this may be triggered yet.
Unfortunately I don’t have the time to debug this either right now, but I hopefully will get this tracked down by the end of the week.
