It appears that upon an NPC being killed by a zombie, they aren't killed properly. They'll persist after a short time in a half-dead state, which appears to confuse the zombies as they try to attack the already dead NPC. Soon after they'll despawn, along with all their loot. This issue only happens when a zombie kills them, as when a player makes the killing blow they die properly.

Additionally, to my surprise, it seems some zombies are having the same problem. In the video you can see a blue shirted zombie with long brown hair be killed, but suffer the same issue. I'm unsure what special conditions it'd take for it to happen to zombies, as the majority of zombies died properly at both my and the NPC's hand.

- Only mods are Bandit NPCs, Day One, and Mod Options
- On a hosted server
- No server settings changed outside of adding the mods

- Upon trying single player, the NPCs die properly, leaving their corpse with loot.
- When I was testing with additional mods, it made it where NPCs won't despawn at all. The poor souls were screaming constantly as they were being eaten without end.
- After removing the Day One mod and only using the Bandit mod, I found that the problem persist.
