Most of what I read is that no one ever found how to disable body bag loot entirely from vanilla npcs 

i found one single post last year where that changed, but go figure they didnt bother saying what the plugin was

Anyone have ideas on if a plugin that does this exists now?

the idea is that the server players get their guns loot and ammo etc, from entities (boxes, crates, bradley crates etc) only. Not body bags, ever. 

always felt like NPC killing to get guns was too OP. Without mods maybe its ok. But the problem is super amplified when tons of botspawns and zombie plugins come into it lol. Like, why even go after events when vanilla bots might drop some AKs. We have gun crafting disabled through Ccontroller thank god

Hey,

BotReSpawn gives full control over what ends up in the npc corpse.
You can set it to wipe attire, belt, main, block rust vanilla loot, and prevent held weapon drop.

NPCKits from the same site can be used to get the same control over vanilla npc corpses.
