When adding the MultiplayerSpawner node, the Spawn Path property needs to be set to the root (Main) node. This is not in the instructions, but it is shown in figure 11.13
Edit:
This isn't listed for any MultiplayerSpawner that gets added, so I'm not sure if it's an omission, a difference in how it's handled in different versions (I'm on 4.2) or a random setting that I've changed.
