Starlight accolades not working

@LAT1207 
To rule out anything that may cause issues are you using any type of mods or custom content.
What platform / version are you using to play the game. PC/Mad or console? 

In my experience the starlight accolades are a bit fickle at times. The nominations are random and are not always awarded for the acting career. My non-famous Sims have been nominated the first time they have written a book or their first painting. The only time any of my actor Sims were nominated was prior to the stage in the aspiration where is was needed to advance to the next step. There does not seem to be a particular trigger to make it more likely to be nominated or to receive an award.
Best advice is to try traveling to the awards and hoping they get the award.
