Changing voice of note causes other notes to disappear when rests are missing
Nightly d45cc19, Win 7 / MS 2.0.2, Win 10.
The attached MuseScore file is an extract from a larger one created by MIDI import (original midi file is also attached for reference).
Select the bottom note (F) in the last chord of bar 1. Now change the voice of this note from 1 to 2 using the voice 2 button (Ctrl + Alt + 2).
Expected result: Note changes to voice 2.
Actual result: Note changes to voice 2 and last (voice 2) chord disappears!
This artefact has appeared in several imported midi files and the immediate cause is always missing rests.
