Instance.interpolatedFont inaccurate

I noticed that the interpolatedFont doesn’t match the actual instance because it ignores custom parameters. Is it possible to fix this, hopefully without much negative effect on performance?

What custom parameter in particular?

Filter and rename glyph as far as I noticed.

instance.interpolatedFont from a formerly working script gives this Error now:

File "GlyphsApp/GlyphsApp/", line 3634, in <lambda> 
File "GlyphsApp/GlyphsApp/", line 3632, in Instance_FontObject
TypeError: 'NSKVONotifying_GSFont' object is not callable

Any changes in the API that I need to implement?

Thanks in advance.

What version of Glyphs is that. That should be fixes in the latest version.

OMG, I didn’t get any cutting edge notifications, I think I accidentally unchecked the box for it.

I can confirm: it is fixed (latest) in 1149

Thank you! :raised_hands:
