The fireball bug

// p is the player

// First example using launchProjectile
// Result: Explodes at player location
p.launchProjectile(SmallFireball.class);

// Second example using world-spawn
// Result: flickers for a second, then disappears until it hit something
final Vector direction = p.getEyeLocation().getDirection().multiply(1);
final SmallFireball fireball = p.getWorld().spawn(p.getEyeLocation().add(direction.getX(), direction.getY(), direction.getZ()), SmallFireball.class);
fireball.setShooter(p);
