A Question about Hair

[Killzone]

I downloaded a female Sim from somewhere which had a NewSea hair.

This hair doesn't 'stick', in that when you exit, save and renter a lot the hair changes to the standard maxis default hair...the one you get when you delete a Sims hair from your downloads directory.

This also happens if I change the clothes of the Sim in bodyshop.

The thumbnails of the hair's various recolors shows up as a neked body in bodyshop, CAS and ingame when I use a hack to change the hair.

The hair mesh and its recolors are also in the booty :- http://svs.paysites.mustbedestroyed.org:8080/booty/ts2/newsea/hair029female.jpg

Is this happening because there is something wrong with the hair, or because the hair was cloned from an expansion I don't have, or something else?

I have Sims deluxe, nightlife and OFB

Does it happen with only this specific CC, or only this sim? In that case, it'd probably be a good idea to ask the creator of either the sim or the CC, instead of here.

This happens with all Sims using this hairstyle so its not the Sim that is corrupted. I have 3-4 other one-off recolors of various hairs that this happens with as well, these show up in the custom hair bin. The NewSea hair appears to be binned correctly.

Its no big deal, as I have heaps of other hair I can use, I just wondered what caused it, whether it be a 'fubared' mesh or my game configuration not being up to it.

Edit. Found it with a better effort on my lazy-ass google skills. Seems that hair must have been made using Pets bodyshop and can be easily fixed using this tutorial here :-
