PC Housing turns invalid randomly when second house is built 1.4.2


Steam or GOG
Single Player/Multiplayer
Operating System
Windows 10
Terraria Version
Controls Used
Sometimes when I build🔨 a new house to move in a new NPC the one that my guide:indifferent: lives in suddenly turns invalid🚫 and it doesn't even say what's wrong with it when you press on it with the question mark❔ it only says housing🏠 is invalid🚫 so you have to rebuild the whole thing so its pretty annoying:mad: sometimes and it would be cool:islime: if you could fix🔧 it.

Definitely in agreement here, there's no way to predict the issue or fix a potential bug without an idea of what the housing setup looks like.

Welcome to the forums ClumsyCat!

Assuming you are referring to the houses above your player character, the issue with those houses is that there is no solid block for NPCs to stand on. There needs to be at least one solid (non-platform) block with no furniture placed on it.
