BG Only: Dating - suddenly "Ask on Date" takes me to the neighborhood screen

Of course, since I don't want to do things the easy way.... I've been playing Newcrest, not Willow Creek. Had I played one of the first two worlds, I'd have seen community lots in the world and wouldn't have asked this question. There is no community in Newcrest. Such small worlds seemed like a "downtown" area would be off world, like it was in Ts2. With 5 community lots like in Willow Creek, that only leaves 10 houses! How do we build a community with those numbers!
