We went through all of the items sold for Karma and made them No Salvage to address some issues with players converting karma into coin. That’s probably what you are seeing.
You guys also made all regular (coin) vendor armor/weapons non-salvageable.
I really can’t see why either… if I want to buy 30 pieces of armor and salavage them for cloth, it’s MY money being wasted. There really isn’t much room for exploiting.
