I was going to make another thread about this:
So earlier today before the forum maintenance (or something like that), I had over 300 best solutions, three badges at master level and over 2700 total answers
When I came back, my 'solutions' -count is about 150, all my badges have been downgraded and I only have about 1400 total answers.
When I go to my 'tracked threads', all the threads are still there, but about half of them have 0 as the answer count. However, when I opened one of those threads, all the answers were still there.
