Description
Issue type
File corruption
Description with steps to reproduce
I had to write a tuplet over a barline (in 4/4) so I changed the time sig. to 8/4 and added a bar line item to make it look like 4/4, and then switched back to 4/4. But when I went into the individual parts score and tried to save, the bar that I changed back to 4/4 was corrupted and when I save, it says there is an error on that bar.
Incomplete measure: Part score: Marching Snare Drum, measure 12, staff 1. Found: 240/120. Expected: 4/4.
Error repeats measure 12-end of file
