I've searched and searched, and can't find any mention anywhere of anyone having ever created a fix for this issue. The xivilai run animation is buggy. I'm sure other people have noticed it too. Every time he goes to put his right foot down, for just one frame his whole body changes to a different post/position. What's up with that? Has it ever been addressed? Is it even possible to fix?

...those must be crickets I hear.
