NPC body instantly despawns?

I just wanted to confirm if there is a way to not have the NPC instantly turn into a loot bag when killed? I'd like the usual behavior of a body which eventually turns to a loot bag since bodies are easier to see from a distance

Also, I have switched from RESpawn and while it was not the most configurable plugin it did offer a somewhat better NPC experience around monuments mostly because attacking an NPC would alert others close by and they would begin to push and in some cases, flank around. I find many NPCs just run back and forth on a line until you get close to them then by default they shoot with too much accuracy which I will have to tune

Ok, I think I ahve managed to find the answers here but maybe if I can just have it confirmed (tho some tests will likely confirm this for me) 

The control of how each NPC will 'despawn' is set in the NPC profile it looks like: "IsRemoveCorpse": true,

It also appears that NPCs do trigger group attacks using these variables: 
  "GroupAlertEnabled": true,
  "GroupAlertRadius": 50.0,
  "GroupAlertReceivers": "",

So I guess there will be a lot of configuration needed to mkae things a little more realistic
