When a player exits and re-enters the game during a match, they can change their stamina.
They take advantage of this vulnerability with excuses such as the internet connection is broken in team matches.
I think save current stamina when we exit the game and it should continue with that stamina when we enter the same room unless a new match starts.
Likewise, Admins can use this to their advantage and throw themselves into the spectator and drag them back to their team.
In this way, they renew their stamina.
