My only issue with popped items is people bot popping, I've had my run in on people bot popping the Lizzard in Mis. coast Abyssea and Chloris.

And you can tell when they do it especially when the ??? appears a second and its gone, I can't compete against people who do that and i cannot GM because what proof do I have other than them staring at the ground where the ??? used to be.
