Hey! i wanna report a bug about your plugin
for starts when u wanna remove your config folder and add new streams as u mentioned above all the old ones return too sometimes more than 1 so it saves the files somewhere and in this case it wont load ingame anymore 

The plugin will merge all current radio stations with the config. Simpily deleteing the config wont work since the convar with all your links will still be there and get repoduced on load. You will have to use the /stnclear command to clear all stations if you want to wipe your config.
