I've been getting odd bug reports for the mods I've made that people who've installed the game with the DVD version to a directory other than steamapps/skyrim/ can't see the items I've added. They're not getting mesh load error boxes, or untextured meshes, they're simply invisible.

Apparently people aren't getting the bug with any other mods that add new items and it's just mine that do it. Some .nif files reference new textures, some already existing textures, it doesn't seem to make a difference. I'm at a bit of a loss as to what could be causing the problem.

Bump for hope.
