entity despawning when spawning another one.

here is a video showing it: https://youtu.be/7azKZ5AN6Hk

and here is the queue.New() code:

// New returns a new queue.
func New(name, address string, skin skin.Skin, pos mgl64.Vec3, rot mgl64.Vec2, srv *server.Server) *Queue {
	q := &Queue{
		srv:        srv,
		name:       name,
		address:    address,
		immuneFrom: map[world.Entity]struct{}{},
		p:          player.New(name, skin, cube.PosFromVec3(pos).Vec3Centre()),
	}
	q.p.Handle(&handler{q: q})
	l := world.NewLoader(16, srv.World(), q)
	l.Move(pos)
	l.Load(1)
	srv.World().AddEntity(q.p)
	q.p.Move(mgl64.Vec3{0, 0, 0}, rot.X(), rot.Y())

	queuesMu.Lock()
	queues = append(queues, q)
	queuesMu.Unlock()

	go q.startTickingQuery()
	go q.startTransferringPlayers()
	go q.startTickingNameTag()
	return q
}

I am on the latest commit, and it used to work fine like two months ago
