Im having a problem getting credit for the artifact challenge "Equip three champions with 3 5* or 6* artifacts".  Ive equipped three at least with these items and Ive only gotten credit for one.  I definately have this issue because I spent over half a million equipping a champion with the required 5* artifacts and I get nothing.

I tried to report this through the game but the support ticket wasnt working either.  I filled it out and hit send and I get "all fields must be filled" error.
