CustomVoting is now backwards compatible with versions since 1.14!
Added support for older versions until and including 1.14.
BACKWARD SUPPORT WARNING: Using an older version than 1.18? Make sure your data.yml does not contain items that don't exist in your version yet. If there are any, and the plugin shows an error on startup, please remove the items or the whole "items" section from your data.yml and restart your server or use /votereload!
Please report bugs in the Discord channel, thanks!
