Legion Commander's hero challenge "Reach 100 / 150 / 200 bonus damage from Duel wins." is bugged for me. Does not track duel victory damage, completion was not rewarded at the end of a victorious game.

Had 340 Duel Damage at the end of my victory in a normal AP matchmaking game, did not get credit for any progress on the 100 / 150 / 200 Duel Damage hero challenge which I had selected. 0/100 was marked in game like it's trying to track stage 1, but the 0 value was never raised.
