Glyphs crushes when adding Instance for each Master

I’m making layered font with 36 masters. When I want to add Instance for each master in the Instances window the app crushes. When I reopen it I don’t get the Send Report option.

Glyphs 2.1.1 (768)

Can you send me the .glyphs file?

Yes.

Now I can add any instances… so I can’t generate font.

After dividing masters to two glyphs files I can add instances. So it is a masters count limit problem.

There is no master count limit. It has to be a different problem.

I get that app doesn’t have a fix limit but the problem occurs over a particular number of masters.

I found the problem. There was a fix limit to the number of masters after all. I increased it to 50.
