Miscellaneous: Female models don't all have a relaxed animation

[Balimon]

Some female models don't have a 'relaxed' animation where they drop their hands to their sides. As far as I know all the male models do this. Some of the female models do but not all. This is easy to check and verify, just by making level one characters. Is this is a feature? Unfinished code? A bug? Curious what the deal is with this issue.

Dwarf, gnome, halfling, iksar, ogre, troll, all work.

Human, dark elf, high elf, barbarian, erudite, half elf, woof elf, do not work.
