NPC's not damaging Buildings

Hello, I was hoping you could guide me here, i have the NPC's with the following you've set. Yet when i hit them, then run into a wooden base, they will throw plenty of grenades into the building, but the grenades will not damage anything besides the player. Also it seems they will not defend themselves against other NPC's no matter what i set with them, they will not target mobs from "BotReSpawn" or "ZombieHorde" for example.

          "skinID (0 - default)": 0,
          "Mods": [
            "weapon.mod.flashlight",
            "weapon.mod.holosight"
          ],
          "Ammo": ""
        },
        {

          "Amount": 10,
          "skinID (0 - default)": 0,
          "Mods": [],
          "Ammo": ""
        },

Hi! They will raid the house only if there is a building block in the house.

Grenades do not cause damage to buildings

Yes, you're right, NPCs won't attack other NPCs. Because it can cause a lot of conflicts with other plugins
