Save save save, but freeze still loses everything

I don't have any screenshots or anything for this, but, as I am sure you are all aware, musescore crashes. A lot. This doesn't usually bother me that much, as I save very often. However, this evening, composing away, saving very often, when the program happened to freeze, and shut down. Which is all fine and dandy. I start it up again, and choose "No" for "Do you want to recover?", because since I saved so often it shouldn't've been a problem. I lost two hours worth of work, inexplicably. When the program froze, I made certain not to touch anything that might be misconstrued as "yes, I want you to delete all my work and so I save the deletions."

Just putting it out there. I can't be the only one.

Gute nacht.
