@MiyuEmi - I didn't know that the resort would persist after changing it to a community lot; so, hmm, I don't have problems with it in my game as I just never go there. I spend lots of time fixing up and playing Hobarts and just ignore those other two. Now, I'll have to play again and visit those old resorts! I seem to spend lots of time deleting those silly bushes and trees that are underground. I think that doesn't always stick either.
I found that if I played the pregnant sims, I could have them quit work and change their clothes. When I am in control of them and not playing with a mod that lets pregnant sims go to work, then they play well. So I leave that option for others.
@Okblondee7 - MiyuEmi is correct. It isn't a world, it's just a saved game. So you'll see at the bottom as an option to play one of your saves from the main menu.
