On left how the bones look after import in persona, on right original setup. I painted few red arrows, so you can see where is original bones and where is after import.
It does not affect skin data, and the rig is working fine. Is this intentional behaviour or bug ? It would be nice if the rig in persona would preserve original bone positions. Now it might be bit confusing when you try to find right bone and it is moved in some strange place.
