Actor Blueprint Duplicates Accumulate at Location (0,0,0) When Using NPC Spawner with Custom Cosmetic configuration

Summary

Actor is automatically instantiated in the level when it is added to the NPC Character Definition in an NPC Spawner. Eventually, there are dozens of these at the same point on the map (location 0,0,0).

Steps to Reproduce

  • Add an NPC Spawner to the map.
  • Create an NPC Character Definition.
  • Create an Actor to modify the Cosmetic of the NPC Character Definition.
  • Add a skeletal mesh to the Actor.
  • Set the NPC Character Definition with the following settings:
    • Type: Guard
    • Behavior: Default Behavior
    • Cosmetic: Custom Character
  • Add the new Actor, retarget from Fortnite Character, and add a Retargeter.

From there, Launch Session, eliminate a couple of NPCs, and when you close the session, you will see that a copy of the Actor blueprint has been added at the location (0,0,0) on the map within the editor.
If you have more than one NPC Spawner or test the Launch Game multiple times, more of these Actors will accumulate at that point.

Expected Result

You should have one or more instances of the actor within the map, at location x0, y0, z0.
Not an instantiated NPC, only the actor blueprint.

Observed Result

I noticed at this point that I had more than 80 instances of the same actor. When launching the game, it generates a copy, and these keep accumulating. Since they are not the NPC, they are not animated; it’s just the actor with the skeletal mesh stationary at that point.
