I remember it was strange, one because I had trouble remembering which one was what, they all somehow look so similar and then because there was this thing that you have twice the same thing, only separated by one being human and the other one elven. I don´t know how it is sorted actually. was it separated into human/elven or into own/other that would lead to different sortings depending on if you are elven or human....
Anyway you can skip the trouble with the vault by selling the vaults and using PPs instead
It´s still the same in the inventory, but if you PP all 4 goods, who cares lol, just PP until no more numbers on he next tech are red
At least that´s what I did haha. I had no patience to fool around with that stuff.
