After working for almost an hour on one of my font files, I saved my file in .glyphspackage format by mistake (dammit). Now I can’t open the file because Glyphs 3 opens up this message error. Please let me know if you know how I could recover my glyphs, I already tried changing the file extension to .glyphs and it doesn’t work, also tried opening the contents of the package in finder and tried to pull each glyph into a new Glyphs file, doesn’t work. I would really appreciate it if you could help me finding a way to fix this.
