But that’s not the point here. It’s not adding mounts to the achievement which are usable on the character I’m checking.
My mount tab showed 507 mounts, the achievement 454. I then got a mount from an island salvage box and one from buying heroic DF both of which I learnt and used.
The mount tab showed 509, the achievement still 454.
Then I made a mount in ZM, learnt it and used it. The mount tab showed 510, the achievement went to 455.
I thought the achievement was stuck, but obviously not as Buzz counted while the other 2 didn’t.
