I just got the achievement A Cool Twenty Years and it did not give me the mount :Coldflame Tempest like it supost to do i have logged out and disbled addons but no mount
I completed “A cool twenty years” on my mage friday night, i got the mount and used it and even flew around.
Weird part now is when i logged my mage friday afternoon the mount is gone, greyed out in the mount list, while the achievement i still completed. Something is weird.
I completed the achievement today, and no mount at all… not in bags, not in mail, not on mount list???
Fixed an issue where players playing multiple accounts could receive two Coldflame Tempest mounts. The second mount can now be deleted.
You’ll have to wait for them to replenish the supply of anniversary mounts 
Also very funny how not receiving a mount is lower priority than receiving two.
Hey hey,
Looks like a few players were caught off guard with this mount going straight to inventory, but we’re not seeing any actual issues and it seems the reporters in this thread have found theirs as well in the end!
