First let me explain that I always save a new version of a project with an incremental numbering scheme (i.e. MyProject1.cpr, MyProject2.cpr etc).
I’ve recently had a problem with Cubase 10 (Mac) where the recent project list is, shall we say, not as recent as I’d like. In other words, the last project version I saved yesterday is not shown, and instead I get an older project version. If I’m not paying attention, I will open the top project in the list thinking it to be the most recently saved version. However, for whatever reason, it turns out it is lying to me. Imagine my horror when I realised I may have been working on stuff that is not my most recent edit!
The only reason I can think of that this would happen is if Cubase crashed on quit, so it doesn’t “remember” the actual last project version name/number. However, I have received no warnings from macOS that Cubase crashed. Nor are there any recent crash dumps about it. So, I don’t really know what’s going on here _(".)_/
Conclusion: for safety reasons I will only ever open a project via “Open other…” (or from File>Open, or double clicking the project file itself). I will never again use the recent project list in the Hub/Project Assistant for this purpose.
I just thought I’d put this out there as a warning for others so you don’t fall into the same trap I have.
