The NPCs are quite broken because when I was just making a sword for my customers , an NPC appear right in the making zone and tryed to come in , but the NPC closed the door and it looks at the door.When I try to open it , the door doesn't open.
Is your shop open and the door opened? I would suspect that the Customer saw the door closed and made an attempt to access your shop from the back. That shouldnt happen and ill make sure its fixed in the patch.
