Just happened to me too in a ranked game. Happens at about 25:30 w match 23492884. Was in base tanking a Pocket ult and when I ult to stop Seven's ult I die.
Yea I just had the same issue too. Wasn't able to damage guards or walkers, but I soloed a base boss set and I got 0 obj dmg. Match ID was 22357679 and I was Mc G.
