Hello everyone,

So I think the topic's title and the description explain the bug I encounter in the game. I have 2 celebrities in my household and they both completed the World Famous Celebrity aspiration so they have the "Unstoppable Fame" trait which prevent their fame to decay. But when I played today, the game notified me that one of them has lost a star and the other one is about to loose her 5th star as well.

I have no mod installed, I just had the free camera in build mode to take a screenshot but I removed it before High School Years patch update.

Thank you in advance for your help.

Alex
