I recently made a font using Glyphs (I am now using Glyphs Mini because my free trial ran out), and the font has no built in bold (I only made one weight). When I export and install the font, certain characters (like h and 1) have strange outlines when bolded. I’m not sure whether this is an auto-hinting error or what. Any ideas?
