“An unknown error has occurred” (Core) after changing Metrics

Glyphs
1

I have been working on a pixel font where I changed the metrics to fit the glyphs, since the ascenders were far too large for the glyphs. I scaled the metrics down to fit the glyphs well, but when I come to export I get the error message: “An unknown error has occurred”. What could be happening here?

I’m currently running a 30-day trial of the latest version of Glyphs 3, so a swift respone would be very appreciated!
