Items moving after save
From the Spanish forum.
When moving articulations or tuplets brackes/numbers, moving one causes others that have been moved to move also. Saving the score also causes items to move back to where they started. The score was initially created in version 3.1 and the problem was first seen when it was saved in 3.2.
Personal note: I've noticed similar results since 3.1 when it comes to hairpins.
