Cannot get NPC to sync

Issue description

I am unable to sync the position of my zombies. All examples out there only spawn players but none spawn NPCs. I am trying to have the NPCs be under the authority of the server (since that is the only thing that makes sense), but regardless I cannot get the position of the zombies to be sync'ed by a multiplayersynchronizer node. I get no real errors except this message, which looking through the C++ I cannot find out what I am doing wrong:

E 0:00:05:0399   on_spawn_receive: Condition "parent->has_node(name)" is true. Returning: ERR_INVALID_DATA
  <C++ Source>   modules/multiplayer/scene_replication_interface.cpp:596 @ on_spawn_receive()

Steps to reproduce

Just run the project, shoot the zombie and you will see that they report their positions and they are not the same at all on the server as opposed to the client
