Hey, the plugin dont work anymore for me (my server)... i dont hear anything since update. Before update it has worked fine... Anybody know why? No Errors or something...

I'm also not able to hear any music from mine. I believe the last update has broken the mod.

For some reason it seems that it isn't finding the controller with the way it currently gets the vehicle in the button press code. 

If you add a line in the code (per below example) that gets the mounted vehicle directly, the buttons now work.  Please note this means the button will only work if mounted, regardless of the config setting - but it's a good enough workaround for me at the moment.

        private object OnButtonPress(PressButton aButton, BasePlayer aPlayer)
        {
            BaseVehicle theVehicle = aButton.GetComponentInParent<BaseVehicle>()?.VehicleParent();
            theVehicle = theVehicle ? theVehicle : aButton.GetComponentInParent<BaseVehicle>();
//  ******************* add this line below ********************
            theVehicle = aPlayer?.GetMountedVehicle();
//  ************************************************************
            if (theVehicle)
            {
                RadioController theController = theVehicle.GetComponent<RadioController>();

                if (theController)
                {
                    if ((config.MountNeeded && aPlayer.GetMountedVehicle() != theVehicle) || !theController.NetIDs.Contains(aButton.net.ID))
                    {
                        return false;
                    }
                    theController.ChangeState();
                }
            }
            return null;
        }
​

I tried this and got this error but maybe I put it in the wrong place
