3212: Error when exporting intermediate layer glyphs

Hello, in 3212, there is a new issue with intermediate layers. I tried exporting a variable font in which a glyph has an intermediate layer. I got the following error:

-[__NSCFNumber _fastCStringContents:]: unrecognized selector sent to instance 0x8...

This works fine in 3208.

Can you send me that file?

I’ll try and dig it out of my git history. It was fixed by just writing the layer coordinates again.
