You have to socialize with her afterwards and there's a roll that you don't see, but a success gives positive dialogue that advances the story.For some reason I can't seem to trigger the Goonies quest despite spending 10+ sessions with Rosita.
Is there an unusual prerequisite that I'm somehow missing?
You don't save money on that at all. AFAIK house maintenance cost goes up by 5$ per slave regardless of where they sleep. The dorm is fine, the 1st level of upgrade is not expensive and gets rid of the happiness penalty.Is there any downside to having all the females in the household sleep on your floor once you get them to undying affection? Figured I could save money on house renovation as long as I'm not recruiting too quickly if this works
Sleeping on master's floor does have effects, I don't recall exactly what they were but I think they're somewhere in the wiki. There was some chance of increasing the Submissive trait by 1 point if you met certain criteria (low willpower, at least).
You can throw in more beds to a bedroom, and each bedroom can house 4 people without being crowded.It doesn't really matter I guess. If you don't plan to keep them, anywhere goes. If you do, simple bedrooms cost 500 and have room for 2 npcs.
Unless there's a better plan I'm not aware of. Most of the household sleeps in the dorms and didn't notice serious drawbacks.
