Entity doesn't appear after send packet, which spawns that entity

Hello, I have a strange problem. I have a method that I call the command. Same method I calling while player join to the server. When doing it from the command works, but when doing it anywhere else does not work anymore.

Code (yes I know, is weak :c):

Code:java

public static void respawnGuild(Player p, Guild g) {
        HashMap<Guild, Integer> ids = sends.get(p.getName());
        if (ids == null)
            ids = new HashMap<>();
        Location l = g.getCuboid().getCenter();
        l.add(0.5, 2.0, 0.5);
 
        double x = l.getX();
        double y = l.getY();
        double z = l.getZ();
        if (ids.containsKey(g)) {
            int id = ids.get(g);
            int newId = getId();
            ids.put(g, newId);
            PacketUtil.sendPacket(p, createDespawnPacket(id), createSpawnPacket(newId, x, y, z, 51));
            sends.put(p.getName(), ids);
            return;
        }
        int id = getId();
        ids.put(g, id);
        PacketUtil.sendPacket(p, createSpawnPacket(id, x, y, z, 51));
        sends.put(p.getName(), ids);
    }

Sorry for my weak english, I'm Pole!

 

We need your createDespawn and createSpawn Packet methods Because we can't tell how the packet is constructed just with this information

 

Ok, I solved the problem. The reason was bad entity id. Thanks for help
