After you post or advertise an offer, it’s posted in the Trade section for 120 minutes.
However, if you got only 1 item, after a buyer purchases that item you sent, the offer (advert) will still be pending on the Market, even when you have 0 amount of such item/s.
This should be fixed!
Screenshot example: (If you hover on a blueprint advert, where the prices are - if the item is sold and now at 0, it will still not be removed!)
