Issue with plugin

Hi,

This code I am using to make it possible to sit on oak wood stairs no longer works correctly after 0.16.

PHP:

<?php
namespace seat;

use pocketmine\Server;


use pocketmine\plugin\PluginBase;
use pocketmine\event\Listener;
use pocketmine\entity\Entity;
use pocketmine\math\Vector3;

use pocketmine\network\protocol\Info as ProtocolInfo;
use pocketmine\network\protocol\RemoveEntityPacket;
use pocketmine\network\protocol\SetEntityLinkPacket;
use pocketmine\network\protocol\PlayerActionPacket;
use pocketmine\Player;
class seat extends PluginBase implements Listener{   
public function onEnable(){                   
 $this->getServer()->getPluginManager()->registerEvents($this, $this);
$this->count = 10000;

}
public function onPacketReceived(DataPacketReceiveEvent $event){
$pk = $event->getPacket();
switch($pk::NETWORK_ID){
case ProtocolInfo::PLAYER_ACTION_PACKET;
$player = $event->getPlayer();
if(isset($this->counter[$player->getName()])){
if($pk->action === 8){$ppk = new SetEntityLinkPacket();
$ppk->from = $this->counter[$player->getName()];
$ppk->to = 0;$ppk->type = 0;
$player->dataPacket($ppk);
$pkc = new SetEntityLinkPacket();
$pkc->from = $this->counter[$player->getName()];
$pkc->to = $player->getId();$pkc->type = 0;

Server::broadcastPacket($ps,$pkc);

$pk0->eid = $this->counter[$player->getName()];
$ps=Server::getInstance()->getOnlinePlayers();
Server::broadcastPacket($ps,$pk0);
unset($this->counter[$player->getName()]);
}
}
}
}
public function onTouch(PlayerInteractEvent $event){
if($event->getBlock()->getID() === 53){
$player = $event->getPlayer();
$pk = new AddEntityPacket();$this->count = $this->count + 4;
$pk->eid= $this->count;

$pk->pitch = $player->pitch;
$pk->metadata = [
                            entity::DATA_FLAGS => [
                                    entity::DATA_TYPE_BYTE,
                                    1 << entity::DATA_FLAG_INVISIBLE

$ps=Server::getInstance()->getOnlinePlayers();
Server::broadcastPacket($ps,$pkc);
$this->counter[$player->getName()] = $this->count;
}
}
}


When u tap a stair, it still shows up a minecart and the minecart isn't set to invisible.

Anything I can do to fix this? Many thanks
