What behaviour is observed?

(I’m not sure if this is related or not.) When a player joins the server (Lobby), they are teleported to the End world (PlayerJoinEvent). If they are a premium player, they are automatically added to the queue. Since the queue is empty in this example, the player is instantly transferred to another server. On the main server (which runs the Overworld), no errors occur. After some time, the error occurs.

What is the expected behavior?

How to reproduce?
