Is there a way to get revived ghosts forget about being ghosts?

Hello.
On this website link of an article about the Mimsy, who is one of the Von Haunt Ghosts this has been written

I

If she eats an Ambrosia as a mean to get back to life, she'll be a normal Sim again, yet she'll still keep her ghost abilities, like scaring Sims or possessing objects.

Yes, I can see that. But most of all I wished for her to be able to age up and die sometimes. As she is now, she can't. The game tells me, it's because she can only die once.

Back from the game. I made a "Houdini" on my Matilde, sad to let her go, they were so madly in love! First I downloaded a Mimsy sim from the Gallery. The best was together with Bernard, so I had to delete him as well. Then I moved Matilde out, and moved in the Mimsy, looking exactly like her, and a normal sim. This made a special start of their marriage, which I have to do all over. :) I love this game and it's challenges.

Mimsy when revived sometimes only looses the Fire Ghosted trait but there is another ghost trait that needs to go, this is a hidden trait and i found it when using MCCC manage traits/remove trait section remove that and your good to go, if you a going to cheat Mimsy being revived using MCCC then make sure you get rid of the fire one first then the hidden one after, doing it the other way seems to crash the modify in CAS option
