When I first logged in I got the achievement you get for logging in again after 7 days despite logging in a day ago. I then noticed my level dropped, I had 178 drills in the dojo and my next lesson had gone back to hiragana 'y's when I was starting on katakana. I also noticed the community threads of the last week are not there, it is like nihongo master has gone back a week? Was it reset with the crash that happened yesterday when nihongo master was down for the day?
Has anybody else experienced something like this and is there a solution?
