tuplet brackets connected to two staves, moved up a staff, causing score corruption and crashes
I suspect this might be related to #278943: Can't copy nested tuplets to last beat of measure.
This score has a lot of nested (three of three) tuplets. Now it looks like every single bracket has somehow moved up at least one staff.
If you look at the one on Violin II, measure 4, I can't drag it down where it belongs, because no matter whether autoplace is checked or not, the staff adjusts to it's placement to keep it above the bottom Vl. II staff and above the top Vl II staff. If I delete it, it deletes the tuplet in the Violas, and corrupts both the Vl. II staff and the Viola staff. Since I can't copy paste, rewriting these tuplets is a lot of work.
All of the invisible brackets are brackets I marked invisible when they were around the tuplet they were supposed to be around. They were fine then.
