Child loses relative location

I have a weird thing going on. Four terrains that switch in and out. They are using the exact same heightmap. Three of the four copy a building correctly, but the other one uses it's local position as it's world position. They are linked, with the building being the child. Did the exact same method for the other three terrains. I THINK I have tried everything, including restarting unity. The building still wants to be out of bounds.
