I did, but I don't see anything in there that prohibits moving households into the my households tab from the other households one? Unless you mean the completely unaltered part? I didn't really think adding households to my households counted as an alteration, since all it affects is culling and map icons, and usually these challenges are too short for culling to take place anyway, I've mostly just done it out of habit, plus it helps me notice when new households move in since they'll have a grey icon. I can definitely stop though, but I'd rather not be DQed from this challenge (and the last one, actually, since I did it there too) over such a minor thing.
