Solved Cancelling Entity Tracking

Hello,
I'm trying to provide a vanish option with a plugin I'm working on,​

and part of being vanished, is being vanished to mobs.​

I've tried...​

Code:java

 
    @EventHandler
    public void onEntityTarget(EntityTargetLivingEntityEvent e){
        if (getConfig().getBoolean("CameraMode.PlayersInCM.AreInvincible") == true) {
            if (e.getTarget() instanceof Player) {
                if (flyplayers.contains(e.getTarget().getUniqueId().toString())){
                    e.setCancelled(true);
                    e.setTarget(null);
                }
            }
        }
    }

But players are still being targeted by slimes and ghasts,​

and if already targeted, will continue to be targeted even while vanished. ​

Other than that, it works fine. Players vanished, will not be targeted.
What could I do to improve this? ​

Anyone?

I'm sure there is a way to stop players who are being tracked from continuing to be tracked.
I'm sure of it. ​

Further digging, I came across this depressing thread...
