Mod looks fine in CK but not when in game, even with all other mods disabled

[Callumite]

Pretty much the title, I am working on a combined mod of two of my previous mods that both alter sanctuary. The mod looks perfect in the CK but when I load up the game some textures and models are missing and I have no idea what is causing it.

 

I have included a link to an unpublished file containing the mod below and if anyone can figure out whats happening that would be great. (credit will obviously be given to helper outers)
