Yeah, in Version 1.26 (?) there was 'Next Day'. They then changed it to 'Next week' in the next version. I think it does make more sense, since they got pregnancy and girls maturing into usable girls to work. The timeline did change, but really it didn't effect much. (Still max 8 customers/shift ect)
People close to death? Get them out of the catacombs/don't work them on both shifts if they are not 100% constitution girls. Working the streets/catacombs/caring-breeding beasts can easily get a girl into a situation that smashes their health down, so beware of that.
Also, if you don't wanna micromanage all these girls and still have them do those jobs, get a matron.
