Description:
Nick traded a scorching killer exclusive to Arz for a scorching bicorne, a secret stash, and a harvest hallmark. Other items may have been involved, but I don't believe they would be of importance. Confronted him on his outpost trade, linked above. He was dismissive and insulted my intelligence. :[ I wasn't planning on making this report until that point.
Anyway, negligence about a trade of this gravity is silly to justify. I honestly just want to hear his reasons for making the trade. I hope it's not, "Oh, I forgot to check."

Let me know if anything is unclear.
