I just got back to Lakeview Manor and both kids were playing outdoors. Weird thing is, Sophie was "naked" (in underwear). I fixed this by giving her a dress and I guess it's not such a big deal but it kind of made me feel uncomfortable. Last thing I rember doing when I interacted with her was giving her a "green dress" and when I came back later boom, she was in underwear. Maybe I'm too sensitive but I hope that get fixed.

If you give the kids more clothes, they'll put them on sooner or later. That's what I did.

if you give them clothes of the same color they are wearing
it seems the clothes go invisible
easy fix just give them a different color
