(They also fixed the bug where you have to break up with Gale to be with someone else even if you aren’t dating him.)
My strongest memory of the original Baldur’s Gate is softlocking in the prologue on my very first playthrough because it turns out that the Infinity Engine 1.0 has no mechanism for scripted cutscenes and no “essential NPC” flag, so if the game needs one NPC to kill another NPC it just makes them fight each other in-engine, with dice rolls and everything, and it’s completely possible for the wrong NPC to win.
Looking over these patch notes, it’s clear that certain traditions have been honoured.
