What Is The Deal With Ghosts??

I usually release the sim's spirit after they die to avoid random ghosts in every public venue around town. I know it's not the best option for people who may want to keep the ghosts of their dearly departed around as part of the family, but it works. Really, after my first experience with being haunted by ghosts in TS4 (shortly after they were added to the game), I realized that they were dull and just started releasing them. (TS4 ghosts really need more ectoplasm to them...)

I play a lot of ghosts, but all those ghosts I have in my households died before the C&D patches, and the new ghost culling system would seem to only work well with anyone generated after the patches. The next best thing I could think of to keep them at bay is that if you do still keep their urns, keep them in the household inventory. I believe it will keep the ghosts at bay, though I could be way wrong. Ghosts in TS4 and their mechanics confuse me to no end.

Well, pre-patch... Putting the urn in your inventory wouldn't prevent them from being culled, it'd just stop them from coming out and spooking it up on the lot when night came around. Non-played sims that died still existed, just without an urn. While they were still around, they would add toward the population limit until it reached the cap, then the game would cull them. The way the game used to cull sims was first ghosts, then unplayed living sims from oldest spawned to recent spawned from what I remember correctly.

Now the system is different and I don't understand the new culling mechanics. :/

As for ghosts, I've been slowly shoving my many ghosts into households by family to try and keep them sort of, "together"--But that doesn't really do anything but declutter my household management window. A few of mine still appear at clubs, but I have a lot of townies so it kind of rotates between living and dead. The dead usually come around when the living sims retire for work or go home LOL. I do use MCC so it changes the sims in the venues to work that way so I don't bump into the same sims everywhere.
The only way for them to not appear is for them to not exist, I think.

Most of my actively played ghost sims live in a haunted mansion aside from this dead kid I got from the Wishing Well. He lives a very spoiled life in my legacy's ancestral home :^)

That poor, dead child though.
