Re: Celebuserum
@Seleos13, do you play with any Mods or Custom Content (CC)?🤔 If you do, some of it could have become outdated with the last patch/update to the game.
If you use Mods/CC please do the following:
1) Move your Mods folder to your desktop.
2) Delete your localthumbcache.package file in the game folder
3) Fix the game in Origin by logging into Origin and go to your Library, then Right-click on The Sims 4 and choose the option to "Repair Game". Wait until it fixes all your packs and not just the base game.
4) Now when you turn on your game it will create a new, empty Mods folder. Check your game to see if that helped, by adding your Mods/CC back one at a time, checking your game each time (unless you really have a lot, in which case the 50/50 Method would be better.)
5) Once you find the outdated Mod or CC, you will have to see if the maker of it has an updated version!
Also, I have noticed that I won't get my fan mail or other items if my Sim is not at their home lot when it is time for the mail to arrive. Have you been at home with your Sim when it is time for the mail to come?🤔
Finally, I check the Bug Report forum and didn't see your exact problem but I did see a similar one: https://answers.ea.com/t5/Bug-Reports/NEEDS-INPUT-GF-CelebuSerum-stops-all-mail-after-move/td-p/7488021
Did you happen to have your Sim move after she or he got this perk?🤔 If so, it could be that you aren't getting any mail, not just the Celbu Serums! 🤨 If you play your game longer and don't even see bills coming in the mail, then go to the link above and click on the "Me Too" button at the bottom of the first Poster's post and then add your experience in a post at the end of the Bug Report .😇
And please update us on what you find out! 🙂
