despawn() will not work if the NPC is in the middle of respawning

[PrettyPrincessPotato]

Describe the bug
When calling npc.despawn() while an NPC is already dead, the NPC will not be removed as expected.

To Reproduce
Create a script with this:

npcDeath {
            despawn(10)
        }

Kill any and all NPCs you see
Watch as they respawn.

Expected behavior
This should allow NPCs to drop their loot, but never respawn.
