Opened game and Sims clothes and hair are all gone
I'm afraid to open my save because the Sims in my active save are shown in the main menu without clothes or hair (mostly- one has shoes and one has a robe?), and I don't know what's going on. All my packs are correctly shown as owned (though when I first opened the game, it said I didn't own some packs that I did, and the Sims didn't even appear in the main screen. I exited and relaunched the game and this is what I saw.) I have relaunched multiple times and it is still like this. No mods or cc active.
Sporty_Bookworm1 Ok, since you are not using CC and have checked to see that all packs are owned, did you check to make sure that none of them are disabled? From the household name, it looks like you merged the Harris family from Eco Lifestyle and the Specter family from Life and Death. All the undies, robe and sandals are base game so it could be that you've got everything but base game disabled.
If you do not have any packs disabled, then I suggest you load the save and look in CAS and in live mod to see if the sims have hair and clothes. You won't mess up anything by opening the save and looking as long as you don't save over the save. Idk for sure, but if you have been testing that new feature, the image of the household may be false, and everything is all right. And if everything is all right, then you can save again, and the Main Menu portrait should correct itself. If you choose to save, then use save as and create a new save just in case. It might take doing it more than once.
Hope this helps.
