Standalone packaged build problems. Common troubleshooting tips?

I found the problem. The game mode will only be created and use once the client starts. I just changed the default game mode to game mode base and re-parent my other game modes from that one. So on start the StartMenuGameMode which is a child of game mode base is overriding the default game mode (game mode base) and then when I start/load a game, my WorldGameMode which is also a child of game mode base will be overriding. I have my data in game mode state which my WorldGameMode has and my menu gets the game state and displays that data. It now displays correctly because my WorldGameMode now calls the BeginPlay event which I have initialize the data.
