I don't know if this is the software or my computer and my habits, but I tend to keep very large scores open as I'm writing to reference ideas made on other pieces. For example: had to compose a piece for philharmonic orchestra, and am currently scaling that down to a woodwind quartet. This involves me cutting/copying and pasting and moving around both scores quite a bit. Musescore will, at the least, start to slow down and at the worst I've been in the middle of working and the app will shut down and I lose all progress. My main problem is I just lost a score I need by tomorrow morning because it crashed while I was working on it, and now that piece won't open. It keeps saying it's unreadable. Is there any way I can recover it?
