Can it be rolled back? I wish. Don't know about you, but I'm on PS4, and all you can do is hit Option to look at "update history" on the game from the home screen. But instead of an actual history, it just shows what version you've currently got installed. And "search for updates" isn't yielding anything; EA needs to patch their damn patch. I'm guessing other consoles are the same, and you'd need to be on PC to actually roll back anything.
I'd barely played the game a day or two, just have to wait for an update before attempting to continue the story. In the meantime, there's the training mode and maybe Fleet Battles, but I'm a total n00b to the game and would get smoked in the non-AI ones at this point.
In other words, welcome to the future! Same kind of crap happened when I recently tried to play Bloodstained: they came out with a big update that caused the game to crash at the main save point/hub world and certain menus, don't know if that ever got resolved. Not EA in that case, but that's just how gaming is now.
