Working with interpolatedFont and Import Font

Hello, I am using GSInstance.interpolatedFont() for some processing upon export. Additionally, I have an “Import Font” parameter set, which imports some glyphs into my font.

However, on export (generating from the instance at interpolatedFont.instances[0]), I get an error message indicating that the features include unknown glyphs – the glyphs I import.

Any way around this?

Can you show the full export code?

Thanks a lot for the call. For those wondering: When you make a copy of a font which has an imported font, you need to do copied_font.reloadLinkedFonts_(None) in order for the imported glyphs to be correctly present.
