By that I mean, you can't just make a 17 year old female human and get Commerce Partner's running animation since the server and animation.anievent(?) hasn't set normal females to use that animation over the regular running animations. So most of commerce partner's nongesture animations should stop working if you were to modify the files, unless you wait for a fix on NA's part to finish the menma AI server-sided. But the point is, changing her defined species type didn't allow people to fight while mounted, since Godwrath1 knows people who have been able to do that.

Completely lost, but don't really care about the subject of commerce partners. :c

Modding racedb.xml, as you said, does fix the weapon/shield glitch. But it doesn't let you fight while she's on your back and it robs her of her special running animation.
