I have a weird problem at export with this file.
notdef BUG.glyphs.zip (140.2 KB)
When I set the Variable Font Origin to “Regular” I get this error :
Problem generating Feature Variations
In glyph: .notdef: Master is outside of the interpolation space at 50 and axis rage: 90–90
Light, Regular, Medium and Bold masters have been generated from instances.
This issue don’t occur in last stable version.
