It’s game breaking bug for me and enough for me to finally quit this game. Reminded me too much of dead island when it came out. I play on PS4.
So, I was in free wooden sword training with Bernard and after a long while I say 30 min, he no longer attacks, he’s just holding sword and will dodge but otherwise you can beat on him without worry. I surrendered to exit the arena no problem. I went to do some merchant stuff and came back to him for more training, this time just combos training. This time around when we’re in the arena, he’s just standing there holding an invisible sword and not doing anything, so I can’t start or finish the training. (By the way, I had completed this training before but wanted a refresher). So now i’m Stuck in the arena with him, and I can’t exit the arena, I can’t access my menu (inventory map etc) and I can’t save, literally stuck in there with Bernard and all I can do is to run around and beat him. I don’t think the time is moving and I don’t even know if he’ll leave and free me in any case when it gets dark, so I just wasted another couple of hours… due to numerous minor bugs I had lost too many hours of my time already getting to this point, so I think this is god telling me to move on and leave this game behind. Too bad, I rather liked the game too.
