Oh cool, under housing there is a card... Never noticed that!
Forest Base is basic, hasn't been updated in a long time, ruins is a modernized mansion...
Both have all necessary facilities for girls to eat, sleep, take a break, interact, and solve temperature issues...
NOTE: On official download Vanilla 1.0.1 not any of the repacks, unmodded, so I don't know if there will be any conflicts (doubt it though)...
Sometimes, unsure what causes it, in the ruins mansion, on the left side stairs, you MAY need to walk around the rear of the chicken coop to access the field/farm sometimes...
