It's because 3dmotion you didn't Add warrior, mage,vampire, etc lines there
Check fixstandonmounts app , Eurion gave you the link or check my release under this comment; )
Tip : I recommend use version 2 because it has help page to know how to use it and later try version 3
**** Version 3.1 will be released soon, it fix all mounts in ur client with only 1 click; ) ****
I hope next time you try search for your problem before post here ; )
Good luck ^^
