Hi,
So if a plugin uses onPlayerCommand and the command is not present, then the player gets a red message "Unknown Command /commandstring !" message.
This is great if your plugin only has one listener for onPlayerCommand.
If a plugin utilises multiple onPlayerCommand listeners and the command is present in one, but not in the other, this message is displayed alongside the output, which is shouldn't.
Maybe it's better to let plugin creators handle the unknown command error message themselves or maybe have an override somewhere to turn these off, or detection of the registration of multiple listeners?
