Corrupted score

Don't know what happened or went wrong, but a good half of my score is corrupted. Before I had issues, I kept having strange error where measures would only let me insert 1 quarter note into a 4/4 measure. I quit and reloaded and suddenly half my score was bad. I thought I'd attach the broken score. It's, uh, weird. Some of the broken measures are before rehearsal marking 13.
