I suggest suspending the Hulk event until it gets fixed. I’m stuck for the next two days unable to play it (as are many others, I understand) because of some bug apparently linked to an unintended early unlock of “A New Ally.”
I guess those with the bug just got ahead, they got access to all missions as others just a few days earlier. And now run out of them, but not missing a single sub.
I can’t speak for everyone, but I was never able to access the Nevada mission. If the event were suspended, then everyone would have a chance to play the same missions without losing ground.
Edit: I freely admit that I may be misunderstanding how this event is structured.
