Said weapon mod was created using the CK and I used the CK to try and change it. I could 'draw' the sword and swing it, but the model was still attached to my back as if it were a sheathed two-handed sword. I managed to change the properties to the right values (I think) but the model was. When I tried changing it from a two-handed sword to a one-handed sword, it worked. I'm new to the whole modding sort of thing, so I figured I'd try tinkering around with a weapon mod I like so much.
