I don't know anything about modding, but I know I get annoyed by sims who are not intelligence sims complaining because they became a plantsim, werewolf, zombie, or a vampire. I would like a mod that removes the want to be cured for the infected sim and for their family members. I would also like the fears of becoming those to be removed.
I don't use witches much, so I don't know if they have the same wants/fears, but if so if you could remove those too that'd be great!
I just hate self hating sims. You're undead, deal with it.

Having the actual cure in the game is fine, I just want the wants removed.
I have Uni, Nightlife, OFB, Pets, Seasons, Bon Voyage, FreeTime, and Apartment Life.
