Export error message / Export VF .ttf

Hello, I keep getting this error message when I try and export this font (other styles have been fine) Broken internal cross-table feature reference in -[FEAFeatureSubstitution(Backend) dump:state:] (FEAFeatureSubstitution.m:181)
Found in: (null).
I haven’t seen this message before, any help would be greatly appreciated.

Can you send me the font?

Do you have a feature in which you mix pos and sub rules?

I don’t think so? The only differences, I found between the files that have exported and the one that didn’t is, I have a brace layer on an Ampersand. If I turn these characters off it Exports perfectly.

I can I will email it to you thanks.

I just remembered what can cause this. If you have a manually written “rlig” feature and also have bracket layers. This is a bug that we need to fix. Until that is fixed, us the “Feature for Feature Variations” parameter in the font settings and set it to “rclt”. That is an similar feature as the “rlig” and should be supported as rlig.

I will try that. Thank you very much for your help.

Hello Glyphs.
I had the same original problem (the error message). So I followed your solution and it worked.

But unfortunately I have another problem: my “bracket layers” does not work on InDesign while it works very well on fontgauntlet…

Is it the “rclt” function that doesn’t work on Adobe?

Thank you in advance for your answer !

Update your InDesign to the latest version. They say they fixed it.

Ok thank you, I will try !
