Hello, just in case this isn’t already a known bug: I’ve encountered two Agarrads in Port Valbury. One of them is stuck in the wall, which is why you can’t see him on the screenshot (but he is marked on the minimap and you can buy stuff from him), while the other is standing next to the stairs in plain sight. They are separate NPCs with separate trade inventories.
Oh it’s known, and it’s our most convincing evidence to date that game code has become sentient and is actively executing its malicious will against us.
