I had made a mod last year to change the appearance of several Spartan units, but the Wrath of Sparta DLC broke the mod.
Now I am trying to make a new one, but I can't edit the appearances of any already existing units in the game.
If I make a new mesh, save it as the name of the unit I want it replace, and then immediately reload that mesh in the kit, it will always show the default mesh.
No matter which unit I try to edit or what changes I make, it will not save the mesh.
If I save the mesh elsewhere it works fine, but I can't make a mod unless they are in the proper VariantMeshDefinitions folder.
If I save the mesh elsewhere, and then move it to the VMD folder, they will load the default appearance.

I have no idea what is causing this and how to fix it. I have tried un and re-installing the kit a few times, deleting all folders associated with it, but the problem persists.
I am running it as admin in Win7 compatibility mode, but that doesn't help.

Does anybody know how to help me?
Any suggestions will be appreciated.
