Seg Fault when remove an instrument on a joined .mscz with mult-instrument parts

I'm encountered this on arch linux x86-64 2.0.2 release and have verified in 3250979. If I go edit->instruments and remove the second harpsichord, then I get a seg fault with terminal output:

Segmentation fault (core dumped)

The stack trace I see when I run 3250979 is:

Staff::idx
Staff::updateOttava
Score::removeElement
RemoveElement::redo
UndoStack::push
Score::undo
Score::checkSpanner
Score::doLayout
Score::endCmd
MuseScore::editInstrList
MuseScore::cmd

This score was created by joined a dozen individual scores via album and had done some edits after (such as creating parts and adding line breaks). If I edit->instruments and remove harpsichord 1 or bass or drums, then I am able to press OK and see the updated score, but then pressing Ctrl->Z will cause seg fault. My parts are [ {harpsichord1, harpsichord2}, {hartpsichord1, bass}, {harpsichord1, drums}]. I would investigate now, but I need to go to sleep. I think the issue might be how the staffs are linked.
