I think i have two bugs:
I had a ranking and it was steady for a few hours since I submitted a while ago with no changes. Now, after i decided to log in with facebook, my ranking went down without playing any further match. I think is actually dealing with it as it is a new submission.
I can only see myself on the leaderboard, it doenst show the people ahead or below of me. I remember a while ago I could see the top players of each team and then fight them to check my code against the top players. For some reason, it doesnt appear to me anymore.
