None of your weapons are showing up in Long War 2

I'd like to report that several weapons have rather glaring texture problems in my game as of late, pictured in this gallery: http://imgur.com/a/jFgBb

I have not tampered with my files in any way, the modded launcher that I use has not reported any file conflicts, and this problem only arose very recently.
As you can see, I am using the XSkin mod to use these... well, skins. But I also did so in the past without any problems.


Although in the event that there IS a mod conflict, the best examples (that I have installed) I can think of are: Mod Everything Reloaded, and the CVWeaponPack and its art assets.
