There was no mention in the latest publish notes about changes to NPC vendors, so I wonder if this is an intentional change, or just another bug? Usually, after a publish, NPC vendors in the town shops have their prices reset to the same basic prices, but this time they've partially reset: the buy-back prices have been reset, but the selling price (what you have to pay them, to buy an item) is unchanged from before the publish. This is most noticeable at Nix's shop in Doom (Europa)! I would have to pay 41gp to buy an arrow, but he will only pay ME 3gp per!!! Now, I DO hope this is a temporary bug that will be fixed soon. I rely a lot on looting corpses, and I can usually recover the cost of a golden skull this way, at the very least.
