AdminMode
From wiki
You can become an admin on your own server by adding/editing the file rights.config
Filename: %localappdata%\Staxel.Launcher\gamedata\LocalContent\right.config Content:
{ "byRight" : { }, "byName" : { "YourUsername" : [ "all" ] }, "byUid" : { } }
Replace YourUsername with your username :)
And then restart your server
