Why did I not get the 30 gold bars that I was promised after winning the last game?

Hello @Karma4412 if you are talking about the gold you receive from the Episode Race then you didn't receive it because there is a long-running issue with the Episode Race tgat prevents some players from receiving their gold.

I am afraid all you can do to rectify this is contact King Player Support to ask if they will add the missing gold to your game.
