I love fairies but they make my saves almost unplayable.

 I have several saves with fairies as my main character. If I have them start a task they stop doing it as soon as I leave them alone. I have to micromanage them. The more Sims you have in your household the worse it gets. I just played the every occult challenge where you start with one Sim and add a mermaid, werewolf, vampire, ghost, spellcaster, servo and an alien. I did this after the enchanted by nature pack came out and I had my fairy households. Everything worked perfectly. To complete the challenge, I decided to turn my original Sim into a fairy. Sadly, that caused my Sim to start freezing up and stop doing the tasks I set for her. I love the fairies and their abilities, but I am not having fun, and it makes me sad.
