I have a weird bug that when I generate/duplicate the uppercase letters as lowercase it either fails to save but looks like it has saved but you don’t get the green box saying its exported (see below image) or crashes.
When it fails to save it seems to revert back to the last saved version (meaning I lose all the changes). I’ve kerned the lowercase glyphs 3 times and each time I tried to save it failed and reverted the file back.
I’ve now given up on trying to add the uppercase to the lowercase. Not sure if I’ve reached the file size limit as my file is 36mb.
