joined scores from album lose line alterations
When a user creates an album and then joins scores, the first score is fine. However, in all subsequent scores, all line adjustments are lost; Musescore reverts all lines back to their original default placement, horizontal orientation, and length. This, of course, makes the lines useless: no line is ever exactly right for one's score when you double-click it from the palette, so you make alterations to every single one. Currently, therefore, joining scores is not useful unless only the first score (or none of them) has any lines of any kind. For a full demonstration of this bug, see thread https://musescore.org/en/node/79431 .
