Damn man, there's still a crap ton of bugs in this game. Especially in the add-on story.
In the DLC, when fighting Uel it doesn't really matter if you win or lose, game always ends up in a 'winning' state.
And fighting Dina, if you select 'Still Preparing', rather than not starting the fight, it just starts a different fight than if you were to choose 'Fight'.
If you lose to the 3rd monster pit boss, it totally bricks the game too. It then asks you to save, some incorrect stuff happens & your character ends up invisible, floaty & stuck at the entrance.
And so on & so forth.
