Sim who asks for mark of Edith functionally becomes Edith

I created a female Sim.  She had a Science Baby with Grim.  Then she married an adult Nyon Specter.  My Sim completed Alice's Sorrow.  Nyon went to talk with Edith so that he could get her mark to use in the well.  After making his wish, which was granted, everyone started acting like Edith.  I first noticed it with the female that I created.  Then the toddler (science baby) had the same problem.  Eventually no one in the household to communicate with anyone.  Everyone just screamed at them like Edith does.  I had to delete the game.  {irritation} This was going to be a Legacy game.  I was planning to run it for 10 generations.  I really liked the way that it was developing.
