I love the search function hehe. Great lonely topic here though.
The 'bug' is still there, but I know what's wrong now.
After you have challenged someone for a scrimmage and the page reloads ("You have issued a challenge!"), then it somehow double pasts the teamid in the standings link.
So if you click at I.1 for example after you issued a challenge, and the team id of the user is 111112, the link is ..../standings.aspx?TeamID=111112111112, instead of ...../standings.aspx?TeamID=111112. That's why it sends you to your own standings page, since the double TeamID doesn't excist.
