Cap component reported as defective – I think it is not

I have been unable to generate fonts from a Glyphs file. I get this error

I have the identical glyph in an older document that Glyphs can generate fonts from. I copied and did a ‘paste special’ from this working file to the current one, but get the same error.

Only if I disable all the glyphs that use this cap component I can get the file to generate the fonts.


can you send me the .glyphs file?

I just sent it to you.
