No Gardening Opportunities

I always get the impression that the game does not like Service NPC's added to households, also the sims from the WA worlds, China, Egypt and France, I've either had a sim of mine married one or ask them to move in with my family, and usually there are problems with them, I don't know why. Just out of spite I have saved all sims from Al Simhara to library and I am in the process of re doing each one of them and giving them children, marrying some etc. When I am finished I am going to used them to fill an empty world, and try it with the other worlds' sims, eventually
there will be families from the three WA worlds living together and marrying, having children etc. it will be interesting...
PS Don't you like cats? Cats are cool. And they make great famil....er, pets! >:)
