Hey,
OT features have been working fine for several months. Now I was just editing some glyphs (without changing anything in the features) and noticed this error.

I have an older version with exactly the same code and it works perfectly fine.
Does anyone know what this is and how to fix it?
Thanks.

Also the Glyphs Forums are usually a very good place to ask this kind of software specific problems.
The glyph is not missing and I did not update the Glyphs app. So that's not it.
What I find weird is that if I copy the same code from the older version (that works fine), into this one, I still get this error. If I delete this bit, where the "error" is, everything's error free.
Already asked in the Glyphs forum. Let's see if someone can help.
• Eliminate the space after the "s.beg_commaaccent" and before the bracket. The white space shouldn’t matter, but you never know.
• Similarly, you could try deleting the line return at the end of that line and reinserting it. If somehow that line return got formatted incorrectly (LF versus CR, for example) then this could be throwing off the compiler. Just a guess.
These are both long shots, but you could try. Good luck.
Also, this has nothing to do with that error, but FWIW, in future it would be more conventional to name your alternate glyphs as sacute.beg, scaron.beg, scommaaccent.beg, etc., so that PDF reconstruction could lead back to the original codepoint.
Unfortunately none of those 2 things worked
Also thanks for the naming advice.
