Thanks Heavenfall.

Another thought - essentially in the end what I'd like to do is to mod the entire CoreWeapons, CoreArmor and CoreItems XML (mostly the first two) so that most goodie huts and lairs don't give out the same crap you can get by simply researching through the Warfare techs - I am seriously tired of leather armor .  I assume that if I mod all the lairs and goodie huts to give out items from a new Treasure StrVal (like instead of "common", change it to "common_more") that as long as the items have a RarityDisplay of "common_more", it should grab from a list created out of those items.  What do you think? Should that work?
