Glyphs can not open OTF/TTF which it exported

I have a Glyphs file which I can export, but Glyphs 3 can not open the exported OTF/TTF file. This error is shown when opening the exported font file:

I could reduce the bug to this minimal case: Test.glyphs (1.4 KB)

The problem seems to be a substitution rule of the following format:

sub a' [x] [x y] [x] by b;

Glyphs 2 can open the files as exported by Glyphs 3.

That’s already been fixed but awaits the next build :slight_smile:

Thank you, good to know!

I can confirm that this issue has been resolved in 3.0.2 (3047).
