Hey there,
I just tried to export a font where I replaced one glyph with a custom one. Within the font there are quite a few symbols. When trying to export I get the message “There are some glyphs with many (anchor) points. The creation of sub-routines can take a long time.” (translated from German).
The font is not showing up in the folder it should be. I’m also not able to see if or how long Glyphs will take to export. Did anyone of you run into this issue previously?
Thanks in advance
