I installed the latest version and I got to say I love the new city feature.. Got a few suggestions though. I asked Lydia to worke in Whiterun and everything workes out as it is supposed to. However, since the chance of finding a client depends on their arousal level. most of the time she just sits in the market. When she does she just takes him home, enter exit and thats it. Tha part is fine, I dont think you can change anything. The "problem", is when the player is inside the house. At that time, lydia will go out and will start looking for a client. What I understand though is Whiterun as a cell is not loaded, since you are in breezehome, and thus neither are the NPCs in Whiterun and their arousal lvls. So Lydia will never find a client. I would suggest that while the player is in the house, the prostitute assigned for that city, will return with a random NPC from that city in regular intervals (so you can also see here having a few clients while you are there) instead of relying ont their arousal to find them.
