Moving sims 'out' with a household greater than 8

@GemzyX As you might know a 'normal' maximum number in a household is eight Sims. As soon as you use a mod to extend the number of Sims in your household the gam might cull members randomly. This can happen when you go to CAS or when you go to manage worlds. When you want to find a mod for the issue you are experiencing you could also check the creator of the mod that made it possible to have more than eight household members. 

Have fun playing. 😉
