x2mdl moves the root of each object in a model to XYZ=0 during the conversion process. That only changes when the first frame of animation moves everything to its proper place. It was mentioned that this bug had been fixed, but I have no idea which version if any of x2mdl actually contain the fix.
x2mdl also has and interpolation path-finding issue that makes moving parts sometimes twitch into a mirror image of what they're supposed to be. I've had some success with fixing those "twitches" by changing the keyframe placement.
