Update metrics lotery

Strange behaviour of “Update Metrics” in Glyphs Version 2.3b (838). I’m not sure does it depends on something, but sometimes it is working, and sometimes it is absolutely not. Via shortcut Cmd + Ctrl +M, or via dropdown menu. Annoying.

Can you be more specific? Can you send a Screencast or the file?

Will try to catch it.

I sent you one in an email.

And another one.
