OnPlayerLoot not working?

So I have this code in my plugin, and there are no errors, but when I loot stuff on the ground, none of them fire.

I'm pretty sure if it's ground loot the first one (with a 3 in the Puts) should be fired, correct? It doesn't seem to be working :/

Code:

void OnPlayerLoot(PlayerLoot lootInventory, Item targetItem)
        {
            Puts("OnPlayerLoot works!3");
        }        void OnPlayerLoot(PlayerLoot lootInventory, BasePlayer targetPlayer)
        {
            Puts("OnPlayerLoot works!2");
        }        void OnPlayerLoot(PlayerLoot lootInventory, BaseEntity targetEntity)
        {
            Puts("OnPlayerLoot works!1");
        }
