I have noticed that the split wood roof corners cause storage below them to be "outside". This does not seem to make sapiens sleeping under them outside, just rottable items, like flowers/roots used for medicine. The flat incline roofs work fine, but just the corner ones have this effect. (not sure about tile/brick as I haven't reached that level yet. Explained my dissapearing supplies as they rotted in a few days, not a few years.
