Campaign mode still not fixed

When will the devs fix the Campaign? I brought this game to play the Campaign and co-op with a friend against AI.

But the campaign is simple unplayable. Everything is broken and the AI script is simple not working. And this is valid on ALL missions, not one or two, all of them have the AI script broken.

So when will they fix it? Did I wasted money on the game because the devs will simple abandon the Campaign mode?
