I was testing the mod out in creative mode, looking at all the structures, and found this house can spawn on the nether roof. I think it is safe to say that this is not intended behavior

nope this is the indented behavior since I wanted to give a solution to people stuck on the nether roof. I made it because that happened to me so many times that I just thought that the structure was a fun solution and it was when the mod was still so small that it was just for me and my friends. Maybe I will remove it or maybe not
