Player Object Not Spawning

I have my player prefab in the network manager as the "Player Prefab", but it does not spawn when a client joins the game. It does work for the host, but no players are ever spawned when they join, they only throw the error "Spawn scene object not found for 1" from NetworkIdentity. I have tried it with the player prefab in the spawnable prefabs list, as well as without it being on the list. The prefab does have a network identity.
