I know you probably don't see the humor in the situation, but really that's just hilarious. If ever a game deserved to be reported to staff though, it would be this one.

Probably the Games department.
In one of my online games I moved for black (I was normally playing white). It said it was my move and I could only move the black pieces. In fact, my name was also on the white side. So I submitted and now I can not move the white pieces.
What happened?
