Hi! I have problem when adding new NPC, this is the first time I encounter this kind of problem because when I add new NPC 1 for example, I can buy on it but when I add another NPC 2, I have a problem, item on NPC 2 doesn't showed but I already check many times no problem on server and client side. Here's some screenshots!
