Guild Wars 2

i’ve noticed with new materials and recipe, when you lf it, you see a price for example i see sheet of ambrite 300 gold, then i click on them and i see the real price… it happen only at me?

No, its a common bug for new items that appear on the trading post and it started a couple of weeks ago.
It seems that new items on the tp only show the very first listing of the item in value and supply in the search result window for about a week or so. Within the first week, you actually have to click on the item to see the updated details of price, supply and demand.

Its the same, if you want to sell a newly introduced item on the tp. In your sell tab you will see the item listed, the demand and the highest buy order for it. But the window will only show the demand of the very first buy order and its value listed. As soon as you click on the item again (to enter a sell price), demand a prices will update.
