The user
(37130) has not been able to arrange scrimmages this week: he can normally challenge other teams, but nothing actually appears in his scrimmages page and his challenges, i presume, never arrived to the other team.
He tried with a lot of different teams (i would have liked to see what happened if i challenged him, but when he contacted me i already scheduled a scrimmage). It seems that he is clearly suffering from a bug, a nasty one as he is going to probably miss a matchful of playing minutes this week. Please look into it, thanks :)
