Unauthorized to Summon Mount

[Ventos]

There was a similar problem reported on the Beta Forum, and I am also quite upset since it happened in the beta with my Lecagy Chocobo. I used the whistle, placed it in my hotbar and it was darkened in it, and it said I could not mount that chocobo, but I could still used the GC Chocobo and Gobbue. When I removed the Legacy Chocobo from my hotbar it disappeared from my mounts menu and I lost it. No whistle, no legacy chocobo.

Update: When I logged in yesterday the legacy chocobo was in my mount menu, my problem is solved. I hope your dilemma gets solved quickly Ronin.
