Pasting or changing score messes with accidentals

Issue type

Engraving bug (incorrect score rendering)

Description with steps to reproduce

1. Write music with several notes affected by one accidental in the same bar
2. Copy and paste somewhere else
3. OR (as I learned today) change from 4/4 to cut time
4. Some notes end up with the correct pitch but have change from e.g. Db to C#

Supporting files, videos and screenshots

Fritiof i Arkadien.zip - see bar 37 (there were more but I started correcting them before I realised I should report the bug and now I can't find my backups - sorry)

Additional context

I thought I had already reported the pasting issue since this has occurred for me for years, possibly since MS2.x even. I can't find anything about it when searching here however, so I'm adding it to this report as well. What's new (to me) is that after I added cut time, the same bug happened - suddenly several of my parts had some accidentals flipped. It's not all notes and I can't find a pattern for when it happens.
