event hero complete-problem

I complete each of the daily challenges of the event hero mode but they gave to me neither the ribbon nor the assassin character.
I dont know if it is for the message that to say that the kills of mg were going down to the half and does not complete the 100 kills or that still they have not updated the profiles (the last challenge I did more of 1 hour of hero mode in spite of the fact that with half an hour) but since already they spent a day couple tape-worm this doubt
From already thank you very much
The text this one translated, I hope that he understands himself
