I would have thought you were joking, but that last part really does prove that you got forced out of the theater. Vision wound up getting killed twice, once by Wanda, and then again by Thanos after he rewound time. You wound up seeing all of the non-evaporating deaths other than Vision. After that, the only name characters who didn't fade away were the original Avengers, Rocket, War Machine, Nebula, and Okoye (I think that's her name, Michonne from Walking Dead). Black Panther's sister was off camera so there's no word on her.
