Just a suggestion. today i see someone scammed again with this old, but still working trick! scammers still use backpacks in tradewindows to scam players. Sometimes happen... so, lets say: You put the item that want to sell in the trade window, the buyer put the backpack with checks inside, open the backpack and you see the correct amount of golds, and see its all ok. After this, the seller close the trade window, you put again the item in the trade window, the buyer put the backpack and say it wont open now, and he dont know now. so the seller, honestly,distracted or unobservant, click ok, and inside the backpack there are no gold checks, but garbage! what about this simple fix: when someone put everytype of container it'll open automatically simple and fast solution, dont you think so?
