Sometimes a restart of the server is like a blessing for those who like fighting in ring. And after 3-4 fights the /challenge gets bugged. Some people* just like to provoke this bugs. If you type /leave  or  /kill while in the ring, the other player has to do the same thing. So nobody is winning, nobody loses and it gets bugged (when you try to /challenge it says "Fight already in progress" or something like that).
Also you can get weapons inside of that building so you can get killed by some other player* from outside of the ring. Or you challenge a player to fight with fist and suddenly he gets a rocket launcher and the winner is who dies last. And while the /challenge is bugged you can /watch every time and get weapons so you see a few guys 'having fun' with rocket launcher (their fav weapon)
Also while boxing in ring some players* like to punch from outside of ring and it's annoying when you can't move in ring and you lose health because of them. I can't find a perfect solution, maybe an invisible wall around the ring to prevent them from punching.
So:
- /leave /kill  while in ring gets the challenge bugged
- You can get a /gun  in ring and outside of ring
- You get punched by random players outside of ring
