Okay, so I got my chocobo and the choco whistle to summon it. I set the whistle into my hotbar (as I did in P3) so that I could summon it as the push of a button. So I go into the field, press the button, and my chocobo whistle gets used as if its a consumable. Chocobo does not get summoned, and the chocobo whistle is no longer in my inventory. No I have to go find out where to get a replacement? Lovely.....-.-
