Hello! So I was creating a new caste to make rich, upper middle class, lower middle class ect sims but while I was able to set the net worth for the rich sim caste, the option did not appear on my upper middle class one (and all castes I tried to make after). I don't know if I'm supposed to set something and I would really appreciate the help. Thanks

Here's the pic of the options https://imgur.com/czyyHC2

Hi there. What you are describing is an Automatic Caste. That means sims that fit the criteria you specify will automatically become members of the caste until such time as they no longer satisfy the conditions. The screenshot you are showing is of a Manual Caste (Automatic = False). This means that there are no criteria, the player must put sims into or take them out of a caste manually by sim name or by clicking on them.

The Net Worth criteria and other assorted things like filters should return for selection if you change the caste type so that it is Automatic.
