I solved the issue, but still don’t understand why it happened. Apparently, when both voices leave the top staff, the staff or some context or something just goes away at that point, even though it’s in use later? I just added a third parallel voice that sits in the top staff and s1*4 to hold it open, and that fixed the beaming issue. I have no idea why that worked, or why it works in the standalone snippet and not in my original case.
