Limb going crazy in poseball

Good evning everyone.
I have a problem with one of my poses.
It's a pose where the avie lays on the side, and when I play it it looks perfectly
normal, but when I put it in a poseball the upper leg fly up in the air.

I know there's nothing wrong with the script, because it's never acted this way before
with any other animation I've used.

The animation starts in frame 2 and all limbs are rotated.
I've also tried to set the priority up to 4.

The animation is made in AvMotion and can be found here: http://colossus-ws.mine.nu/~ypolt/couch_cuddle_f.bvh

Hmm... for some reason it started working by itself after a couple of hours...
Thanks to those who contacted me to try to help tho
