I had some of our folks take a look and here is what I heard.
Under the Post Game section in the Island Settings, there’s an option for “Game Winner Display Time” that is set to 0 by default, you have to add however many seconds you want there.
The Post Round section also has 2 settings that need to be changed “Round Winner Display Time” and “Round Score Display Time” if you’re using rounds.
Lastly, under the Scoreboard section there’s a “Game Score Display Time” setting that when changed, shows the score after the game ends.
