To reproduce:
1. Open the attached file Crash_Boom_Bang.mscw
2. Switch to voice two (I used Cmd+Opt+2 for that).

The document has been created with two staffs, Soprano and Alto, and a Part has been added that includes Soprano voice 1 and Alto voice 2. The Soprano and Alto voices have been Imploded. This is an odd combination of things, but one that I managed to accidentally create (and then experimentally tried to recreate for a while after).

Also attached is the backtrace generated for this file on my Mac running macOS 10.14.6

I can't reproduce. What note(s) exactly should get switched to voice 2, and in score or in part?

Workaround is to delete the tie prior to the voice change.
Not related to parts pr single voice parts at all
