Bernard combat bug

Bernard constantly quits training with me after a few minutes randomly, and there’s no reason for it. My health is full. It happens every single day , so it’s not some kind of problem with a specific day. I basically can’t train because every time I start training, he just quits after like 45 seconds and walks away. He returns to his post and starts bugging out walking back and fourth. How do I train? Below is a video example of what’s happening. I can’t train any weapon because this happens every single time. Some of the other bugs are not that bad, but in my opinion this is game breaking. If you can’t train weapons, you can’t play the game.

And btw, this happened to me in 2 separate play through’s. I stopped playing the last game and re-started a new campaign because of this issue. The longer I play this game, the more bugs start to manifest. And I don’t mean, the longer I play it, the more I notice. I mean quite literally, the more I level up and progress through the game, the more bugs start to pop up and stop me from progressing. It’s almost like they dev’s are addressing and fixing bugs that manifest in the early game, as most people don’t have the time or patience to play through the entire game I guess. Or , perhaps fixing most of the bugs that manifest in the first 20 hours of game play helps out with game reviews. The problem is, I can’t finish the damn game. How is this appropriate?
