This morning SO asked me to re-login (I use google as the openid provider, associated to a google corporate account - not @gmail.com).
While doing so, I received an "We haven't seen this account before" message. So I was a little worried I did anything wrong.
After that, I was presented with my "regular" login page... except all my badges were lost!
Not that I had lots of them (I had like 9) but I liked them.
My rep points, questions, answers and votes show up correctly though.
Here's my SO profile in case it helps.
