a saving bug ?

If I edit a file (without saving it…) and then decide that I want to reopen the previously saved file again I get the edited file.
So Dorico saves the changes by itself in the original file and only if I close the file completely without saving do I get the unedited file. Happens both when I use the recent file list or open the file directly.
Sounds like a bug to me…?

No, this isn’t a bug: if the file is already open, then Dorico simply switches to the window that contains the file in question. If you want to re-open it without your saved changes, close it without saving it, then re-open it again.

Or save it under a new name and then open the original file?
