populated means there's data in data editor.
The item editor seems to be monitoring the changes in inventory, so if you are at haven shop, simply buy a random starter weapon(balanced dagger for example) and that item's information should show up in the item editor, or to say that the item data is populated. Don't alter anything else, the scanner is all that's required
I can first hand say that CE works absolutly fantastic! it´s not as easy as CH-trainer, but it still works...
What i do not get however, is how to be able to change my Strenght, Magic and Dex stats... i can change Cunning and Constitution... but not those 3 .... it works sometimes, i save the game, and when i reload, it´s all back to normal again... Do you know what i should do? 🤔
