Issue description

When there are nested multiplayer spawners, and when some of the children of the second layer spawners are freed, there will be a node_not_found error when new peer joins.

Steps to reproduce

Inside the reproduction project:

1. run 2 instances
2. click the host button on the first instance, wait a few seconds so the labels in the middle are deleted
3. click the join button on the second instance.
   There will be some node-not-found errors when the peer joins:
   

This does not happen if you delete the queue_free code in level_1.gd

This also does not happen if the client joins before those labels are freed
