I haven't had any luck with that. After using the macros I can see my items appearing in the .txt files in :
...\Data\Editor\Templates\Stats\Generated\Data\Armor.txt
and
...\Data\Editor\Templates\Stats\Generated\Links\Armor.txt
But I don't see them in the Editor/Game. I also made a little test by deleting the "Stats" folder completely and the Editor is working just "fine" without the folder. Item stats are there like before deletion.
Any Ideas ?
