As of now, I can't go anywhere without seeing a giant error "WTF I'm a Missing Mesh" everywhere I look. Everywhere. This is specifically in the Imperial City waterworks where I got off the Alternative Start boat and found everything infested with missing meshes. Also, Imperial Guard NPCs are portrayed as just a floating head and a floating sheath... I'm pretty sure there's more NPCs affected than just guards though, and it really stumps me. I really want to find what is causing the missing meshes so I can figure out what I did wrong.
Here is my modlist/load order.
