What annoys me most isn't the missing content, it's the lack of communication and transparency regarding the issue. A week ago I got a message saying they were aware of it and to keep an eye on their social media.
They haven't addressed the problem on any platform as far as I know despite several players talking about it. Yet they'll openly mention that they are aware of an issue with the singleplayer campaign. It really does seem like they hope we'll just shut up and go away if they ignore us long enough. I suggest opening tickets with support if you haven't already to put more pressure on getting this fixed.
