I just hope the common PS5 bug where dialogue cuts off in cutscenes has been fixed.
And maybe some of the other longstanding issues, such as the bugs with equipping characters at camp who aren't in your party, and the many UI/tooltip errors (such as the DC for your spells displaying using your ability modifier used for the spell's saving throw instead of your actual spell save DC).
And especially issues with game flow between cutscenes, exploration and combat, such as characters dying in your concentration AoE spells after a battle while you're in the post-battle cutscene, or characters not being pulled into pre-battle cutscenes so that their buffs run out while you're in the cutscene unless you skip it.
All these little jank elements should be pretty easy to fix, but currently keep the game from being the polished masterpiece it should be.
