completed sub-zero epic challenge but did not receive the milestone reward.

Same issue here

Same, I hope they fix this. I want diggs for my theme team so bad man.

Yes I have also had this issue is there anyone that can help us with this

I've completed this challenge 4 times now and it's not counting. It's even more frustrating that it shows me the 5 stars at the end. It's such a horribly designed challenge too, why do I have to play with the horrible slow commanders team who can't catch to save their life.

Same here. How can we report this?

Same thing happened to me pisses me off cause I spent like 2 hours trying to complete this impossible challenge.
