Riding Skill Bug

Hello, this is Altpancake from the Icecrown realm.

I would like to report a bug that i have experienced from using my alt character, Shampancake.
I have bought the Expert Riding Skill (225 Skill) and the Blue Wind Rider on my Shampancake account, but my Wind Rider still cannot be used.

Here is a screenshot from my Altpancake character on the said mount (albeit with a higher Riding Skill)

And here is a screenshot from my Shampancake account (with the 225 Riding Skill and the same mount)

Both of the screenshots were taken in the same location, beside the Wind Rider keeper in Warsong Hold.

I tried to use my mount everywhere in the Borean Tundra zone, but to no avail.

All help is appreciated.

Shampancake does not have Cold Weather Flying,

Ah, so it's just a blunder on my part. Thanks for the response.
