AGameSession Overridden Functions Not Being Called

Functions such as BeginPlay that are overridden in a Game Session class do not seem to be getting called.

1. Open the attached project
2. May need to open NewMap
3. Play in new window with 2 players while running dedicated server

Result: Notice that the Game Session is in fact being used in the game mode, but it's begin play is never being called regardless of the fact that it has been overridden and the super has been called.

Expected: Functions overridden such as BeginPlay() would be called on the server where the GameSession exists
