Equip a rare support type champion with 6 life artifacts of level 4 or higher.  

I'm stuck with 2/6 and have at least 8 rare support type champions equipped with life artifacts of level 4 or higher.  I can't advance till this mission is credited  and its been stuck for more than a month.  Asked for help and was told to go here. Request #2278041.  Sure would like to see this fixed.
