If a user receive a message when feed a chocobo reporting is not possible to gain more exp what means? That the max is reached so he/she can pass to the next step.
Is totally unnatural that to confirm the limit of a rank a player have to use the chocobo in battle and is normal to give the onion at that moment!
Why SE do this thing? Is totally not right and too sad like a fraud! No one messago to advert the player
And what is the solution? To use the one refund from SE.
Thanvarian onion is the way to step up so the USE can only means "OK, next step" or "No, error message" and if not in this way is a fraud or a bug, you can choose.
