Crash on autosave after deleting staff from instrument in score with linked parts
To reproduce, create a new score that includes an instrument of more than one staff (say, piano). Go to File -> Parts… -> New All. In the main score, go to Edit -> Instruments… and delete one of the staves from the piano. Go the corresponding part. All looks well. The crash does not happen right away, but rather a few seconds after you click in the multimeasure rest.
