I often get a warning dialogue, saying something like: the file has been changed outside of glyphs, while I’m working on it. I can then choose between “keep” or “reload”.
the warning pops up about five times in a row. after that, when I save to a new file, then close the file and reopen it, all changes are lost.
What is your ‘Use Versions’ settings in the preferences?
I had this happen to me once, but no data loss. And after clicking it away, nothing happened and I could continue normally. Could not reproduce it since then.
It doesn’t matter weather I use glyphs 1 or 2. The dialogue still pops up. It happens everytime after I saved to a new file, that means a lot… I save my files as ufo’s, that said
