Describe the bug
Once a score is sufficiently complex I encounter an issue with playback. More accurately: Playback works fine until i start tinkering with notes. Sometimes newly edited notes become mute. Also sometimes entire staves/bars become mute, even when they played fine earlier. It seems like at memory issue, but I'm not sure. To be clear: This is inconsistent and it's only part of the music that's playing, while other parts are not playing.

To Reproduce
I have attached the file wherein the issue happens. You should be able to reproduce with editing new notes, and repeated playback. However you may need to have the program open ("work") for 20-30 minutes before the issue happens. Also attached image of bars where issue appears.

Expected behavior
Notes should play regardless of how they are manipulated.
