I imported a new module from my Commons account into a class and it merged with a completed module. So when I opened the assignments within the module they showed as complete. I opened some of the assignments individually and they were from another module we had done a month earlier. The two modules are completely unrelated writing modules. When I deleted the new module, it deleted the other module. Now the student's assignments and grades are missing. I had already transferred them to my grade book so it's ok. But some of my kids wanted to go back and look at their essays and they can't. How could this have happened and is there any way to find the information?
