Ultron node not unlocking after completing essential battles

FaustianDeal

I have completed 3 essential battles in Avengers vs. Ultron: Round 4. after completing 2 of the essential battles the Ultron node did not properly unlock.
The Scarlet Witch essential to the right, and the Hulk essential at bottom left both failed to unlock.

same just happened to me in round 3. beat ultron, did essential node with scarlet witch (top one) and Ultron didn't unlock.

I don't know if even more posts saying "same here" are worth posting. But, same here.

Sam, round 5 beat Caltain America sentry node and Ultron still says 7h37m to unlock. I'm filing a ticket, getting sick of the bugs in this event.
