Hi there.
I have a serif typeface with two masters (Thin and Black).
In the exported OTF, the Light weight has a failure on the “h”. Only on Light and only in OTF. Everything is fine in TTF and Variable.
Have you experienced this before?
Can you check the scale of the corner in both masters. If you use a flipped corner, make sure you flipped by the same direction. If that is the case, can you send me the file?
