Version 2.0 (If you find bugs, post in discussion please)
This was a rather time intensive update considering some of the features added required a tedious amount of rewriting and planning. Below you will find a list of added features and fixes!
Added ability to set multiple arenas.
Added ability to run multiple games simultaneously.
Signs are now attached to one game (instead of every sign is attached to one game).
Added config setting to set the maximum number of games allowed to run at any given time.
Added config option to set whether or not player hit detection should be enabled during the game.
Added crash handling system so players will not lose items or get stuck in arena upon logging back into the server after an unexpected crash.
Added player command to list all existing arenas.
Added player command to remove arenas.
Added console output to show operator what data was detected.
Fixed sign handling system not updating correctly.
Fixed a few Null Pointer Exception issues.
Fixed No Method Exception on 1.13Rx.
Removed player name tag changes.
Known Caveats:
No voting system implemented yet, Arena is chosen automatically by the game. This will be updated in the next version.
