Generating fonts from Glyphs app consistently

I’ve been having issues generating fonts from one version of Glyphs app to the next and it seems other people do too:


I wonder what people’s solutions are to keep it consistent other than keeping each Glyphs app version saved for the project, such as using other tools https://twitter.com/cosimolupo/status/719093919745748992

If you need consistent results, you might need to keep specific version of Glyphs around. I’ll try to keep the changes to a minimum but need to be able to make changes to improve things now and then.
