So, in the new patch something called "Maximum Sim Count" was introduced, the details copied from the patch notes are as followed:
A new Maximum Sim Count option can be found in Gameplay Options.
* The “My Households” panel in the Manage Household screen allows easier management of which households are considered important. Households placed in this panel are protected from being… deleted.
* The “Maximum Sim Count” option specifies the number of protected Sims allowed. If the limit is reached, existing households need to be unprotected before new ones can be added.
* The limit can be changed and does include an “Unlimited” option, although this setting is not recommended as it may cause performance issues or other undesirable behavior.
Because these households are "protected from being deleted" does that make them safe from ever being culled?? Does this apply to the entire household line, like ghosts of ancient ancestors or just the ones currently in the family that are active?? I'd be very interested to hear what others make of this and whether it improves your game play or not.
