This update releases a bit earlier than expected because it includes an important bug fix.
The next one will probably take some time as the plugin needs some clean up.

Features

• Fixed "inventory lost" bug when leaving the server while being in an arena
• Added support for Spigot 1.13 and 1.14 (if you come across any issues be sure to let me know)
• Added intelligent command help (beta) and better help layout
  
• Added possibility to set a reward command for each arena
  The reward command will be executed when a player won the game, you may use %p% in your command as a placeholder for the player's name. Make sure not to include the slash at the beginning.
