Warning - Do not trade for stacked items (like Fiery Brimstones) - Current Exploit Unpatched

I have been looking through the "new" queue a bit and I've seen quite a few posts about people being scammed out of their money trading for fiery brimstones. I did some research, found out how to do the glitch, and can indeed confirm, it is an exploit.

Here is what the glitch effectively does (I will NOT be discussing how to actually do the glitch as I do not want to spread abuse):

• You agree to trade for a stack of items (such as 100 fiery brimstones).
• A trade is initiated between the players. In the trade window, the scammer puts in what looks to be 100 fiery brimstones. In reality, it is not 100 of them but the trade window WILL SHOW that.
• The person being scammed will put in their money and trade. The scammer will get all the money, trade away something worthless in comparison (again no details), and you will be stuck.

TLDR: Do NOT trade for stacked items. It does not depend how vigilant you are in checking/not dragging items. This is a graphical display glitch being used to scam people.
