Config file link (pastebin.com): It keeps resetting to the default..
When does the error occur?
Everytime I restart server for a reload.
Steps to reproduce error:
Restart server.

Every time the server reloads/restarts, the config is saved. This overwrites any changes you have made and is intentional to ensure that kit tracking/lives are not lost on restart. It's very easy to fix, so next time you want to modify the config follow these steps:

• Edit the file and make any changes
• Run /pvp reload in-game or from the console
• At this point the new config is in memory and the default should not overwrite your changes

If you ever make changes, simply remember to use /pvp reload to tell BattleKits to take your changes into account. It also has the advantage of not requiring any other plugins to restart.
