I lost a lot of credit!
I turned on my Duolinguo today in the midst of a ten day streak and found that about 20 excercises which I had fully completed are now showing as "undone." I've been slowly working my way through the French for about six months and I've never seen such a mass change...any thoughts?
I was ill and didn't do any refresher lessons for a week. When I returned, I had 22 to do. I started working on them, and every day more appeared. Finally, two appeared that I had completed two days ago. In addition, lessons are appearing that I had to have completed months ago, and I'm supposed to redo all of them????????????? What's going on?
