I can't figure out what is wrong with my poor fairy sim! She always seems to get the nauseous moodlet after eating a variety of foods: goopy carbonara, mac and cheese, PB&J, etc. The food is often leftover from the fridge, but is still fairly fresh and is definitely not spoiled. She is not a vegetarian, and she is not pregnant. In fact, the moodlet doesn't list the cause. (If your sim eats something that has gone bad, it will usually say "from spoiled food" and if she is pregnant it will say "unknown causes.") The most curious thing is that she also got the Good Meal moodlet from the same meal.
I thought fairies might have some kind of dietary restriction, but I didn't find anything searching online. The only other thing I can figure is that it is some sort of glitch. Has anyone else experienced this or know what the cause might be? It's a little annoying that my sim is always running to the bathroom to vomit after meals! Maybe she has bulimia?
