Converting Vacation Worlds To Livable Worlds Y/N?

Unfortunately. Celebrities should be rare occurrences, not part of the everyday livestock. In general, sims living in a given 'world' should stay there. If my sim is in B. Bay, Nancy L & company shouldn't be as commonly seen as cat lady. If anything, it seems that sims that live outside a 'world' are seen more frequently than one's neighbors, which is unrealistic and makes no sense. Festivals might be an exception.
