Something about knockouts at weekly challenges!

Hello!

At the weekly challenge the knockout with headbutt 10 opponents is buggy, they not counted well. I knocked out some players from other teams, but not really count, it's stayed 2/10 only. Maybe it's count randomly, so sometimes yes, sometimes not. One of my friends noticed the same too. Please fix it and in the future in other weekly challenges please test the challenges parts more, or any other way please try to avoid these bugs! Thank you.

Have a nice day!
