Cannot mount dragons/missing mounting animation?

[PervFromPoland]

Title. I have no idea why, but when I interact with a dragon to mount it my character just teleports where she should be instead of getting into the mounting animation and I have no idea how to fix this

video example:

(I know it only shows sahrotaar but the issue persists on every dragon it seems)

Edit: I've narrowed down the issue and it looks like Thunderchild broke the script for mounting a dragon. I'm looking for a way to fix it.

 

Edit (final): Looks like Ultimate dragons was the issue, disabling it fixes dargon riding
