Suddenly cannot save work
Am using Musescore on a Macbook. It has saved 2 other projects just fine, now on my 3rd piece - which has saved perfectly well until I went into page view - when I hit save, it reverts my work to a previous state instead of saving. In fact, whatever I try to do in page view, it reverts my work to something from earlier. Try adding a text box, it puts in the middle of the score and won't undo. Change from page view to continuous view, and it reverts my system changes. Tried saving as, saving online, the shortcuts have greyed out, and just keep reverting the systems. Have I hit a paywall that I'm not being warned about?
