Thank you OH so much. This really helped. Maybe just mention that the button to tag the NPCs is situated at the bottom left of the screen. I had 24 NPCs and it took me awhile to finally find it.
Again thanks alot.
Glad I searched and found this thread, specifically Syn's last post. Not sure if this is known or not but if you go to the main NPC page and click Manage Fitout, it brings you to a different fitout page (only sorted by item category). And on that page clicking the items then the slot they go to does not work. I think it needs to be redirected to the fitout page you reach from NPC control.
