A couple of times, as I’ve been working in a system, when I go to do something, the vertical space in the system above suddenly goes haywire, creating huge spaces between a lower staff and the one above it, pushing the whole system into conflict with the system below it. Undo doesn’t make it go away, but rather, keeps adding space – so the only thing to do is to revert to the previously saved version.
It has happened to me twice, and reproducing the same edits does not reproduce the bug. It seems as if it might be unpredictable. This time it happened when I selected some rests to edit their appearance. The system above (not the one in which I was working) had spacing go haywire.
Is this a known bug?
