[4000] Intermediate Layer coordinates disappear

Just opening a file and saving it in Glyphs 4 makes the coordinates of Intermediate Layers in certain glyphs disappear:

When I enter them in G4 and reopen the file, they are gone again.

Test file: sudo-font/sources-design at width-axis-4 · jenskutilek/sudo-font · GitHub

Thanks for the test file, I’ll have a look and report back.

Only _part.bowl.descender, _part.desc.hook, and _part.desc.hook.left are affected. E.g. g also has a full set of Intermediate Layers, but they keep their coordinates.

I fixed the issue; will be in the next release.
