I'm building a plugin to allow admins to drop weapon spawns by dropping weapons on the ground and then I'm trying to implement a respawn system so that after a weapon is picked up, that weapon will respawn after a certain amount of time. And the respawn is where I'm having issues. Here's where I'm at code-wise (just a sample with a 3 second respawn for testing):

private object OnItemPickup(Item item, BasePlayer player)
{
	var weapon = item.GetHeldEntity() as BaseProjectile;
	if (weapon == null)
	{
		return;
	}

	timer.Once(3, () =>
	{
		ItemExtensions.Clone(item).Spawn();
	});

	return null;
}

private static class ItemExtensions
{
	public static BaseEntity Clone(Item item)
	{
		var droppedEntity = item.GetHeldEntity() ?? item.GetWorldEntity();

		if (droppedEntity == null)
		{
			return null;
		}

		return
			GameManager.server
				.CreateEntity
				(
					droppedEntity.PrefabName,
					droppedEntity.transform.position,
					droppedEntity.transform.rotation
				);
	}
}

The problem is that the item that spawns isn't able to be picked up. I know I'm close to getting it, but this is the blocker I can't seem to get around. Any help would be much appreciated.
