Hi Lost Pine! 🌲😼 The NPCs may still express anger or hesitancy after unlocking parts of their respective maps... They're like that sometimes, it's a combo of the overly passionate part of their yandere personalities + bot brain! We'll see if we can tweak that somehow.
As far as the AI and game dev goes, them being upset after gaining trust shouldn't be an issue as long as they don't immediately kill you for unlocking doors. You can usually apologize, talk them through your process of finding/exiting the room, or change the subject and they'll snap out of their upset spells, even if it takes some persuasion.
