House not working

I created my first house without using any premade stuff, and I just placed it in my main world (I had made it in a separate game play just in case it didn't work out) and in my main game play it is now not working. I'm at a loss for what to do. It works in the separate world I had created to make the house, and now it only recognizes the roof. I have it in Brindleton Bay in the 64x64 lot and it is just not working in my main save. Works everywhere else though and I am terribly confused what's going on with it.
