A particular MSCZ file causes crashes.
The MSCZ file appears to have been corrupted in a way which MuseScore does not detect, but cannot handle.
1) Open MuseScore
2) Load Hair_Medley-3
3) Try to save it (or, I suspect, wait for autosave). MuseScore will crash. (I have send at least two crash reports.)
Much time has been put into this arrangement. I would appreciate some way to recover my work, even if I have to lose some measures to do so.
