I feel like there's a lot about Vintage Story that's really immersive, but one time I'm reminded strongly I'm playing a video game is when the drifters spend hours walking into my front door. I've triggered its aggro logic and now it will move towards me and attack, how exciting. They wander off eventually when they fully de-aggro but only after they've acted like a stuck Oblivion NPC for way too long. I suggest monsters should have a "frustrated" or "searching" behavior when they can't reach the player. At least lurk a couple blocks back so they aren't visibly clipping through the door.
