No *** here, i did the mistake of trading him 67x100 byne bill + 33x 1 byne bill by accident, and that ^$%$)@)_ gave me 'Koh-I-Noor' and took 33x 100 byne bill ....
This mistake cost me 33x100 byne bill to waste...
I did of course call GM, but they say is not a glitch, and they currently using my '1 time restore service'.... I of course send EMAIL to SE about this is not right @ all.
According to the update information from SE's site:
"Trades with the following NPCs involving ancient currencies may now only be completed if the currency amount matches the amount needed to purchase items."
This likely means Fdeath's issue will not happen to anyone any longer unless they trade the exact amount required to attain the particular items, both listed in his post:
"33x 100 = Koh-I-Noor.
25x 100 = Wootz Ingot.
20x 100 = Flask of marksman's oil
12x 100 = Bottle of Cantarella"
While it's nice that such a mishap may no longer be as likely to happen, one might be inclined to think it's practically SE's policy to take care of any likely detrimental issues years after they come to light.
