Copy-pasted sextuplets contain 7 notes, deleting them crashes MuseScore
I'm the using 3.1 Beta release on Windows 10
Steps to reproduce:
-In any score, select any rest or note value and create a sextuplet.
-select the sextuplet, copy it and paste it somewhere else.
-Pasted sextuplet has 6 notes
-pasted sextuplet has 7 notes
Steps to crash musescore:
-Save the file, and reopen it (notice the copied sextuplet is also corrupted)
-select the pasted sextuplet, press delete
-no change from last opening of save file
-sextuplet is deleted
-all sextuplets are corrupted, pasted ones are differently corrupted
if you make sextuplets and don't copy paste them, when you save the file and reopen it, the sextuplets will be corrupted in the same way. Deleting these will not crash the program.
