Third Party PUN Scene Sync not working

I'm trying to make a multiplayer car game. When you click on the Play button, you go to a sort of lobby, while you wait for another player. Once both the players have joined, in theory the players go to the game scene to race. But what actually happens is the first player stays in the lobby scene, and the second one goes to game scene. But there are two cars in the game scene, which leads me to believe it's a scene syncing issue. I was originally following along with the PUN Basics Tutorial, which is why some of the Debug messages don't make a lot of sense.

Sorry, lot of code :/

Launcher script: handles most of the networking

Code (CSharp):

Sorry for not checking the code for you but:
There are 2 demos in the PUN package, which might help: "Asteroids" and "Basics Tutorial" both switch between scenes.

 

I was originally following the PUN Basics tutorial, then I attempted to convert it to my own game...

 

This line might be the problem
