Exporting VF in 3413 crashes Glyphs instantly

Hello, I am trying to use instance.generate(). I get errors all the time:

NSInvalidArgumentException - -[__NSArray0 addObject:]: unrecognized selector sent to instance 0x1e76e3a00

I then tried running the export from the native VF dialogue, but Glyphs instantly crashes. In 3260, the export works fine.

I sent the file.

Can you try 3414?

Brilliant, thank you very much.
