Scores completely deleted when parts are made?
This is an ongoing issue for me. Last year I wrote a musical called Door to Door, and the opening number completely vanished from my computer after I made parts, saved, and quit. I think the issue is that, if I save and quit while I am viewing one of the parts, some sort of glitch in the system causes the file to simply vanish, and all that remains is a .temp file. This happened with a number of other pieces in my show- and really set me back in the process, and then again with almost all of my string quartet pieces, which now only exist in .pdf form. I had hoped the would be fixed with the Musescore 3 update. Unfortunately, I recently had to make an arrangement of Shostakovitch's Second Waltz, to be completed tomorrow, and the same issue happened once I opened Musescore this morning. The file is gone, save for a .temp file which is not readable by Musescore.
What can I do in this situation?
