Probably this should be 16 instead of nominal_zoom+1?

Please give that a try and let me know if you still get your expected results!

(That's for a typical zoom 15 at 512px tile size max_zoom... so if you want zoom 14 you may need to try also setting this locally to 15 instead... but the PR here should be for the generic case.)

Yes, I have previously tried to hardcode there 16 instead of nominal_zoom+1, but I did not get expected results. For me it seems that there should be 17.

it's been a while since I've been familiar with the details, but I expect that nominal zoom (display zoom) is actually what we want here. If features are not appearing, could it be because the features on those properties aren't set appropriately? (Treat this with a grain of salt since I don't have the context)

Yes, nominal_zoom could be a proper solution. But in my case I need it to be nominal_zoom+1, because I do generate tiles for offline maps and I stop at zoom 14, I cannot go to zoom 15 because the file size of offline map will be too high. So I overzoom from zoom 14 to 16 and then add +1 to max_zoom_with_changes parameter. But in a general case where all zoom levels are available it should be only nominal_zoom.
