[1.9] Passengers

Hi, I'm attempting to use the passengers system in 1.9, but when the entity riding is dismounted, it reverts back to it's original position before riding my entity.

Here's the relevant code:

Adding a passenger (in my entity):

private void handleImpact(){
	if (!this.worldObj.isRemote && this.getLassoer() != null && this.getPassengers().isEmpty()) {

		ArrayList<EntityLivingBase> entities = (ArrayList<EntityLivingBase>) this.worldObj.getEntitiesWithinAABB(EntityLivingBase.class, this.getEntityBoundingBox());
		for(int i = 0; i < entities.size(); i++){
			if(!entities.get(i).isRiding() && entities.get(i) != getLassoer()){
				if (this.toofaraway()) 
					return;
				entities.get(i).startRiding(this, true);
				return;
			}
		}
	}
}

Dismounting the entity (In an item, on right click):

	
if(player.isSneaking() && !lasso.getPassengers().isEmpty()){
			for(int i = 0; i < lasso.getPassengers().size(); i++){
				lasso.getPassengers().get(i).dismountRidingEntity();
			}
			lasso.removePassengers();
		}
