Bit of a bump on this but have had some time to explore this issue and i have found the issue, if i double click V4 or any character to load them into the scene i cant get the hair to drape, if i drag them it works.

A strange issue and i would think that it should work reguardless of how you load your figure/prop into a scene, i would report this on the bug tracker but somehow i get the feeling they will just say that draging an object to the menu on the right or into the scene window is the preferd way of adding things to the scene
