NOTE: When spectator mode is disabled, OnPlayerSpawn will automatically be called, if you wish to restore player to state before spectating, you will have to handle that in OnPlayerSpawn. Note also, that player can also go to class selection before if they used F4 during spectate, a player also CAN die in spectate mode due to various glitches.
