Here’s an odd bug…
I opened a font last week and the “e” was missing. I thought I overlooked it. I was busy and didn’t have a chance to work on the font so I left it fallow until today.
Now the “e” is back but the “p” went missing. I know I created a “p” (I know I created an “e” too). I closed the font, reopened and now they are both back.
Maybe they went somewhere to be alone. Seriously though, the above did happen.
