Weird staff break up

Hi there,

Does someone understand why after 91 pages of non problem scoring I suddenly get this weird break in the percussion staff?
It’s an instrument change (from CC to Vibraphone). I have many instrument changes before, specially for this percussion and it’s the only time this behavior occurs.
I think I saw someone mentioning a similar problem on the forum but I just can’t find the thread back.

Thanks for having a look,

I believe this happens when at least one of the staves has a manual staff override (using the Staff Spacing tool in Engrave mode). If you reset the relevant handle (which should appear red), that should fix it.

Yep, that did the trick. Thanks Lillie
