Speed Kart is a default add-on. http://forum.blockland.us/index.php?topic=223980.0
Every time I disable Gamemode_speedkart, then close the server, it seems to re enable itself, even if I delete it it will find it's way back into my addons folder. Any suggestions?
How are you disabling it? Using the Start Game menu, or the config file?
Restart Blockland, don't enable it, done.
