Start/Stop/Pause/Resume has been updated, and the buttons now function properly in doing what they are designed.
Pause/Play now freezes all players on the spot and prevents them from moving. Putting them in spectator mode.
Stopping the game/closing the server now removes all entities spawned by the pause function, as a failsafe in case the game is stopped without purpose.
As per usual only non-blacklisted players are affected by these events.
