Items that a trader-type will purchase?

[AileTheAlien]

Looking at the trader definitions in the game, it seems like the <stockGenerators> tags are what control...their stock / inventory for sale. However, I can't seem to find anything that controls what they will buy. Do traders / settlements just buy anything that they sell?

Yup.

If you want them to only buy something, just add the purchasable good to the stockgenerator with a negative min/max countrange. Or leave blank.
