Summary
Custom NPCs (custom mesh & verse behavior) play the death animation when the same shot that damages them also kills another NPC, such a Fortnite Guard. This can happen when using shotguns, which shoot multiple bullets at the same time.
Since the mesh gets removed, it has no collision with bullets, and the only way to kill the NPC is with explosives or custom damage from verse.
The Custom NPC will still result IsActive[], both on the agent and fort_character through verse, and the behavior still runs normally.

Steps to Reproduce
Place two NPC spawners with custom npc definitons. One should have a custom mesh and verse behavior, the other one should be a Fortnite guard with default behavior.
Make the Custom NPC have enough health to survive a shot, make the Fortnite guard have 1 HP.
Grab a shotgun (best result with drum shotgun or large spread ones) and shoot so the shot hits both.
Expected Result
The Fortnite guard dies, the custom NPC stays visible and hittable.
Observed Result
The Fortnite guard dies, the custom NPC plays the death vfx even though it doesn’t die, and stays alive even though the mesh is removed.

Additional Notes
From my tests, this happens when it targets a custom NPC and a Fortnite guard NPC. Two Fortnite Guard NPCs and two custom NPCs won’t trigger this issue.
I am available to provide more details if needed, since this is a pretty rare bug, but quite breaking.
