I just started Terraria today, and I live in a house that I know for a fact (even though I'm just a noob) is invalid. I built a house for Asher and that went fine, he sits in there all night. I just don't know why I should have a valid house. I don't want an NPC in there, though if there's an other reason i'll let it in. I have know bed yet, so I don't if you maybe need to have a valid house to sleep in one or what. My current house keeps the zombies, demon eyes, and slimes out, so I'm happy.
