If I am not mistaken (which I very well could be), when a player dies, the joints connecting the body parts are broken, including the one that holds up the HumanoidRootPart. Therefore, I believe that the HumanoidRootPart falls through the ground and into nothing, therefore becoming the farthest target and not being followed by the foresaid NPC.

I’d confirm this before taking my word, but one way to test my theory is to follow after the Head of the players rather than their HumanoidRootPart. Inform me of the results.

As a player dies after 5-6 seconds it deletes itself.
If it falls into the void it deletes itself aswell.
