Prefab with navmesh agent teleports

Then to another problem. Some of the spawned prefabs with navmesh agent seem to be "teleporting" to undesired point on the terrain after they are spawned.

I found this:

"disabling the navmesh component works aswell like this guy said and then reenable after a certain time."

and

"disabling the navMesh agent and then using a coroutine to enable a few frames later seems to have worked."

I noticed that there is an option in Pool boss to "enable NavMeshAgent". I suppose there is no delay between the spawning and enabling the NavMeshAgent in pool boss? If not could you add some delay?
