So, I make a lot of offers on trades in hopes that I might get the items/Lions contained in it. The only thing I don't like is, that whenever someone cancels a trade, I'm confused because I don't know which trade was cancelled.

My suggestion to fix the automated message is to maybe make it more like the 'Trade Buyout' message. It should include the user in it, the Lions/items it contained in the trade, and the Lions/items you offered on it.
Please post why you wouldn't support this fix to it. ^^
