1) I had that problem with Elin gunners at first. I swiftly deduced that the source of the problem was an animation replacer I'd been using to swap the normal Elin sitting animation with a "lying down" on (got that from some obscure blogsite iirc). The three files that were causing it were
Popori_F_Hair_ANI.gpk,
Popori_F_ANI.gpk and
Popori_F_Face_ANI.gpk.
Any modified animation files like those are going to need to be updated again (same thing that happened when Ninjas and Reapers came out). Unfortunately I know very little about how to do that, other than that it involves some rather advanced hex editing.

2) As for the human berzerk, I can't really say what might cause that. I don't think the human's armor files were updated anytime recently, so if you've got a problem there, you must be using a VERY old file or something, possible pre-brawler?
You're welcome to have whatever I've got for humans, though. This consists of any mods I've picked up over the years from various sites:

...And you can always export any additional textures from your old .gpk file and import them into mine (if you want).

3) I'm not sure what you mean by
"A lot of the Elin outfits aren't modded it seems at this time." The only way I can think of that they could have been removed by updates would be if you were overwriting the base archives in the
CH folder, rather than using the method of creating a separate
_CH folder for all of these modded files to go into.
