I started a new save file in Moonlight Falls and I have been playing the same family of Fairies for 5 sim weeks and 2 or 3 days. No major glitches whatsoever, just a few little random things:
- My Fairy seemed to get the nauseous moodlet much more frequently than normal for all three of her pregnacies.
- If I direct a Fairy to sleep in a normal bed, they will, but will sometimes wake up part way through sleeping and go sleep in the Fairy House.
All in all, my game has been running smoothly, I've had no issues with gardening at all (I know a lot of people have).
I also have quite a lot of store content installed which all works fine. I have not yet played a Vamp, Witch, or Werewolf so if there are bugs associated with those occults I do not know of them.
