I've already remove all of my mods, but the problem still persist. I've already repair the game in the Origin and recently update it, but my whole sims in my household is still gone and I still can't play them.
This is exactly the same thing that happened in my game (when i tested it with my older mods backup to find the problem) only i went to manage worlds instead of CAS. This is most likely the mod caused save corruption problem. You need to update your mods (CC is fine, these won't cause this issue.) When you save your game with this issue, it persists in that save.
Steps you can try:
1. Remove mods (tuning mods, script mods, custom traits. You can leave CC like; build objects, hair, clothes, custom skins in there if you have CC built houses), delete localthumbcache.package and load your save in game. (Do use a save which does not have this problem)
Wait for a bit around 2-4min for the game to clean your save and save it as a new save then quit the game. (you may need to do this to other saves you intend to use)
2. Put your updated mods (tuning mods/script mods and custom traits) back into mods folder and hopefully the issue is gone. (it was for me)
Additional small step: Check your saves folder if there is a folder named scratch in there. If it is, delete it as it is not needed when the game is not running. (it should delete itself upon game exit but this issue sometimes can leave it there causing problems when playing.)
Also to be 100% sure it is fixed, only CC objects with new or modified interactions need an update (icemunmun's candle making and canning station for example). Check that you don't have any build items with new/modified interactions, if you do, look for an update/confirmation if it is working with 1.58 version. If you don't update these, they may not work properly but still won't cause this issue.
CC Showers can be batch fixed with S4 Studio but even if not fixed, won't cause corruption.
CC Beds have issues in university but won't cause corruption.
