Note that if you ever change active households, even with the game clock paused, the overstuffed one will tend to dissolve on you unless you have StoryProgression protection in place for it as the game itself won't know how to handle such a household. That's not a recipe for sanity though, it's really annoying to have to keep doing, and I would suggest using PP instead. The way to do that is to use the space bar to toggle through the active sims until it reaches the second 'page' of icons where sims #9 and beyond would be. It is possible to play an overstuffed household without NRaas PortraitPanel in place. I do this occassionally just to keep my game running smoothly and error free. So, as suggested previously, reduce the numbers in your household, then, I would suggest doing a factory reset to clean your game as it has obviously become problematic. I am guessing that if you try replacing the metadata or a factory reset one of your sims could be removed to reduce the household to acceptable size. As this is the maximum displayable, I would suggest that you do not exceed that number. (You won't have control of course, but the relationships will persist.) Personally, I do not like having large families to control, I am a micro-manager, but on occassion I have gone to eight. If I were faced with this, I would decide which 'human' sims could be spared and move them into a seperate family.

A bug which will never be fixed now as EA has moved on to Sims 4. Normally a sim cannot get pregnant if the house is full. I have never heard of the game miss calculating.

Nraas woohooer bug
