Piano braces disappear in some flows…

I find it really strange… In the big file I’m working on (19 flows, vocal score of an opera), I find that the piano part looses its brace in two flows, in page view (not in galley view, where the braces are perfectly there) and I cannot find an explanation about it. Any idea out there?

This has come up elsewhere, I’m sure of it (though I can’t instantly find it).

The only solution I’ve found is to either copy all the music in that flow to a new flow (and delete the original) or copy to a new instrument and delete the original. Thinking about it, you could try adjusting the gap between the bracket and the stave (engraving options IIRC) and see if that forces Dorico to redraw it…

Marc, please send me the project so that we can take a look at this problem.
