Re: The Sims 4 Get Famous
I had this issue earlier. I cancelled the event and signed up for the gig again and after 2 tries the artist did it right and the action disappeared from the checklist.
I think the outcome is just down to chance and sometimes it gets a little bugged out.
If you don't want to 'fail' the event you could always save before your sim goes to the event and re-load the save if the game gets stuck.
