Please see the image below. Something happened in 10.1 and now my Void Elf is afraid to rest his legs on any non-Dragonriding mount (and even then, his legs are just as far out, but it happens to “fit” those mount models)! 
UPDATE: Upon relogging in, using my Felsteed and other smaller mounts like the Dark Iron Core Hound resulted in the correct leg/body graphics being used. Only AFTER using a Dragonriding mount did using other mounts look… gymnast-like! 
What a silly bug!
Huh, I noticed that too on this too. I just thought she was spreading her legs like that since she’s on MG haha
I haven’t hopped onto my other characters and since I don’t have a belf, not sure if it’s all thalassian models or just velves.
LOL that is the silliest looking thing I’ve ever seen.
Good god what is happening to this game.
I know, right? Like, this should be a very simple fix: while it does look good on some larger mounts, it should NOT apply to smaller ones. Ironically, this would look fine on the Uncorrupted Voidwing… if I wasn’t so high up on the saddle.
Budget cuts.
lol right? Ya idk what on earth is going on that’s crazy looking.
I feel like unhappy employees are letting all these random bugs go through out of spite.
The new client update fixed the bug.
Id be down for this
10.1.0.49426 to be specific.
It’s not just void elves. Blood elves are also experiencing this bug.
We never, ever skipped leg day.
I have this client version, just logged in and was able to recreate the issue. Note that I updated my original post and upon logging in, mounting graphics are normal UNTIL a Dragonriding mount is used. It has something to do with initiating those mounts that cause future mounting graphics to be bugged. This is true even if you cancel summoning a Dragonriding mount before it completes (i.e. just engaging any of those four, soon to be five, mounts causes a problem in the game code).
This seems to be fixed, fyi!
