That rings a bell. The problem is the kotor tool will not let me change that field to the filename, it will however let me change it to the itemclass row in baseitems, however that doesn't actually make it show up in game either.
EDIT: I was able to make the item show up by renaming the itemclass to the uti files name, but there is no icon like there used to be, its just white
Here is the glow rod entry in my baseitems.2da Default model seems to be fine but default icon is not pulling in the file, I even extracted it and put it in the override just in case something in RCM overwrote it.
