Breakpoints disappear when upgrading site to 2018

[RattlesnakeLady]

I just saved an existing Muse file to the latest version (2018) and all my responsive layouts/breakpoints disappeared. Of course it's the one time I didn't make a backup copy. Why did they disappear and is there any way to get them back?

Not sure, but you may have a look here:

This may sound different in your language, though.

Best Regards,

the 2018 build should auto-save a backup when you convert a older .muse... did you go back in and delete it?
