Recent occurrence with the NESS spawning system

Maybe you folks know why when I set corpses to lootable through the on spawn script like I've been doing for 12 years now they want to drop a corpse, which hangs around an decays, then leave a loot sack? Here's the 2 lines added to on spawn for mobs:

SetIsDestroyable(FALSE, FALSE, TRUE);
DelayCommand(1.0, SetLootable(OBJECT_SELF, TRUE));
