I build a barn for my cow, then an invisible animal shed LOL (retired)

Plan B :)

So I got this barn from debug. It looks nice and old. I filtered via packs and had only cottage living

Then I upsized this pet door

Because a little of the animal shed is sticking out by the barn its easy to click, I cheated the shed dirty and my sim walked right through the barn to go and clean it :D I will look at more debug items for other packs and see what I can find, but I like this very much :)
