I don’t understand the “Stems can’t be zero” error I’m getting on export.
My file was exporting fine. I tried to add a ligature glyph by copy-pasting and renaming an existing one, and something went wrong. I still don’t know what. But now even restoring to an older version of the file still gives the same error, even though it’s a version that I know exported fine just an hour ago.
new file won’t export
older file, exported before, not now
I’m not trying to do any variable interpolation here, but I am using a lot of unusual ligatures.
