To get proper spawns for cars in and make the exhibition match and multiplayer to work if you’re not using my template map, drag as many PlayerStart_TA into the blue side of the map. Make sure it’s at least 50 units higher than the ground. After you have done that, you have to build all or build AI paths! You can also add a Pylon_Soccar_TA and connect the PlayerStarts in it, it has some options to play with.
If the game crashes when you score a goal, add a PointInSpace_TA in the center of the map and set the goal orientation to that.
