this bug has been around for too long through many versions and it’s really frustrating to deal with
Glyphs randomly crash after undoing couple steps, it happens randomly and there is no specific trigger for the bug
when Glyphs reopens the work i wanted to undo is all gone and i have to redo everything again!
I know there are other posts about the same bug and I updated one of them that the issue is still occurring couple weeks ago but I got no response
running Glyphs Version 2.6.5 (1300) on OS 10.15.3
