Creation Kit model/uploading issues

[RagingPigeon]

I've got two incredibly infuriating problems right now;

I have one mod out on the Steam Workshop, and in it I've got a hood and cuirass that, when I test it using the files I have loaded on just my machine (Data/textures and Data/meshes), the hood and cuirass work just fine with any gender and any race. I had multiple complaints on the workshop site though, that the hood wouldn't work for non-humans (the hood is invisible) and the cuirass wouldn't work for females (again, it would just be invisible, though in this case it renders the whole body invisible). I couldn't get this issue to show up on any of my characters, so I removed all traces of the mod locally from my Data folder and downloaded my own mod, and sure enough, the complaints were accurate. So, my issue is that when the Creation Kit archives and uploads the files used for the mod, it's simply not archiving them right or skipping some or something. Does anyone recognize this issue and can offer me a solution?

 

The second issue is I'm working on another mod where I combined two models using nifskope, and I can see the two models just as they're supposed to appear in nifskope, and I can load them into the Creation Kit and they appear fine in the preview window (though one of the two models is slightly translated). When I go to wear the combined model in-game though, one of the models in the combined model doesn't show up. So again, how is the Creation Kit able to see something just fine, but then in-game, it breaks?

 

Any help would be greatly appreciated.
