Amjoie: It should be an option when you click the mausoleum. Well, assuming some people have died. I've only ever seen graves in there for townies and sims I've added to the town myself, as opposed to the vendors, paparazzi, and other random people the game spawns. It has been suggested before that you need to have known the person that died but that has not been true for me. Even pets show up in the mausoleum. That is one reason I have been re-doing graveyards; to make pet areas.
Hanyo: Amjoie is right, you should read through the thread; it is very informative! And Writin_Reg explained it MUCH better then I could. But basically, I believe it breaks routing.
It is up to you whether you want to consider our advice or not. I just wanted to let you know since I was doing the same thing you are, and had to start all over with CAW. It takes so much time and effort! Who knows with this game though, maybe your town will stay lag-free! :)
