Forum:NPC's arn't coming!

NPCs (Like the merchant) arn't coming to join in my rooms I created and I doubt Im doing anything wrong. I want a merchant to move in and I have over 3 gold and I know that's enough for him to show! Same for demolitionist. I have bombs and he won't show either! ''' Help! ''' I don't know what to do! I've done everything right, but they still wont show!

What I have for the rooms:

-Completed wood walls and blocks

-Glass windows

-A door that goes into the room

-Chair and a table (WIth a clay pot on top of the table :P)

I've got everything, theirs no holes or cracks in the rooms of ayn kind. No merchant nor demo man comes. Am I missing something? I don't think I am. Or am I doing something wrong? I waited for a very long time and still nothing! >:( A nusre showed up, but not a merchant or demo man. I don't understand why these arn't coming?

AmI doing anything wrong? Heres a link to a picture of the rooms! >>> [|Picture Pic of the rooms] <<< That design for the rooms worked before? Is it that my world was generated on 1.0.3 and somehow got glitched?
